There is a French word “amplois” which is also used in Russian language, but I couldn’t find adequate equivalent in English.
The idea is that you play particular types of roles. So curious me now wonders what types of roles you guys like to play?
To give a better idea here is the example of myself.
I like characters that wear beautiful costumes, as I’m a bit of sewing freak. My Ravenholme black-with red dress and my Pirate crimson-with-gold shirt are made totally by me.
I mostly play nice characters who do not cause troubles for others and often help those in need. The reason is that I’m not a very experienced larper, and it’s rather difficult for me to be evil even in game. But I’m working on improving this (the Countess in last Ravenholme is an example showing that I am indeed improving
).
I like playing with little things and tools, especially if they involve biology and chemistry. Making alchemy potions in bottles with water and coloured powder, doing medical activities with test-tubes, coloured water, and medical gloves, or applying bandages to people and feeding them with pills (which were M&Ms in little medicine bottles) - this is a kind of stuff I enjoy very much.
Fighting. I am indeed a fighting fan, so I often make fighting characters, and if I carry a weapon - I will use it with every opportunity. Plus recently I found that my character can easily grab someone else’s weapon if it’s left unattended 
I like having connection with another character(s) so that we can do some special playing around it together. Though I think most of larpers enjoy this option, I included it just in case there are people who prefer to make totally single and independent characters.
I’m not a leading role person, more a follower. So being a part of someone’s crew is a good option for me. Being Megilindir’s retainer suited me perfectly, and so does being a pirate in Captain Black Luc’s crew.
I like having IC lover. Or even two. It’s fun 
I like magic stuff and don’t like special combat abilities. I’m not someone who will be taking Tough or Super-Special-Punch, nor I take armour. However, if magic is involve in larp, I’ll definitely take at least a bit of it. Or maybe much more than a bit 
I like to take care of someone IC. Being a village woman who was speaking for the pregnant girl in Stargate was a nice experience. I also like being a bodyguard, this involves not only fighting to protect someone but also watching the space around, checking possible threats, and when necessary - taking the strikes aimed at the one I protect.
Ok, here was my confession, now’s your turn, guys 
I’m listening carefully 
yay making people super-itchy.
