(Disclaimer: I definitely don't think my RP style is the style to end all other styles. So take this write-up with a grain of salt. I firmly believe that everyone should find their own style and run with it. However, maybe this write-up will give you some ideas if you ever feel stumped in your RP.)
Character Quirks Make the World Go 'Round
What makes your character unique? Is he or she a workaholic? Allergic to cats? Addicted to working out? Does he twirl a lock of his hair around his finger when he's deep in thought? Is she a clumsy klutz? What's his favorite food? Color? Song? Is she a snob who thinks anyone from the X or Y is a dirty degenerate? Is he absolutely and 100% terrified of cats?
Work these things into your RP. It'll make your character really come alive for the people you're playing with. Just above all: be consistent. A character who's a blushing innocent one moment and then making crass sexual jokes the very next isn't going to make much sense... unless your character is suffering from some sort of multiple personality disorder. Or is putting on an act.
Be Active Rather than Passive
So, you just walked into a room with an already established RP scene going on. Instead of immediately emoting that you go off to sit in a corner of the room by yourself and wait for someone to engage you, why don't you actively try to get involved? Pay attention to who is where in the room by reading their actions. Maybe someone's standing right in front of the coffee dispenser you were about to go to. Do you politely ask them to move? Do you just walk around them? Do you shove them out of the way because they're in between you and your go-go juice?
Is one of your friends sitting at a table with someone you don't know? Why don't you go up and say hello?
Did someone just ask you a question? Why don't you answer it and then ask them a question back? You're having a conversation, after all! Don't rely on other people to carry the scene for you. You'll have a lot more fun as an active participant rather than a mere spectator.
It's All in the Details
Pay attention to your surroundings. Are you outside? Is the wind blowing your hair in your face? Is the frigid air turning your words into vapor while you speak? Is the summer heat making you sweat through your shirt? Are the large crowds of vNPCs milling about giving you anxiety? Is the glare from the sun striking off your watch while you're socializing blinding the person you're speaking with? (Kidding. But hey, why not?) Are you inside a bar? What music's currently playing? Are you having to shout over the noise to be heard? Did that pink-haired bimbo of a New Yorker just bump into you for the bajillionth time today?
Look at the people you're RPing with, even if they're someone you RP with every day. What if they changed their outfit? What if they're wearing a new accessory? Or changed their hairstyle? Or have a pmood that's drawing attention to the dark circles under their eyes? React accordingly.
When in Doubt... Make a Roll
Your crush just walked into a room right as you were tripping over your own feet and faceplanting on the floor. Why don't you roll a charisma check (roll self cha) to see how well you can play off the whole fumble? A failure would probably result in your poor character being a puddle of humiliation. A success could very well mean you're capable of simply laughing off the whole situation as some failed attempt at trying out a new dance move. Maybe you could even segue into asking them out to dance sometime with the promise you won't try out that move in particular? (More RP!)
Some person on the other side of the room just started gossiping about you behind your back. Instead of playing as though you're all-knowing, all-hearing, and all-seeing, why don't you roll a perception check? In this case, you'd be rolling for intuition (roll self perception). Success? Give that person some judgmental side-eye! Failure? You're clueless. Let them gossip away.
Your crazy ex just threw a rock at your face. Roll for agility to see if you dodge that bad boy.
Doing it in Public is a Good Way to Make Friends
RPing that is! You perverts.
If you ever feel super stumped or otherwise up against a brick wall in regards to your RP, the best remedy is to go out into a public place, set up a scene, and wait for people to show up. Or you could reach out over the public radio to try to lure people to your location. Either way, getting out there and making an effort is the best way to meet new people and progress your character's story along.
Good luck and happy RPing!
