Might end in groping, might end in getting your lips chewed off. It's all about context.

but why tho He's not completely opposed to them, but it's almost certainly going to be fwb/someone who lets him sleep on their floor sometimes rather than a traditional romantic relationship. He's not really capable of that like... at all....... and seriously though, why would you do that to yourself. He's horrible.

Awesome! Vaas revels in violence, whether it's brutally beating someone down or a really satisfying, low-down dogfight - especially if it nearly kills him. He's a master of guerrilla warfare and loves to fight dirty, whether that means drugging his opponent or luring them into traps, and he's got a taste for extravagant methods of killing and torture. Batman villain kind of extravagant.

Quick warning: Vaas is unlikely to hold back during a fight, and will genuinely try to kill or at least grievously injure no matter how small or inoffensively the confrontation started - unless he decides to try to subdue them so he can torture them later, which is a pretty regular thing. I'll always give a head's up if a thread starts leading towards a fight, but keep it in mind when considering threads with him!

Totally fine as long as it makes sense - talk to me about it!

Physically healthy...ish......, lots of old wounds and scars, has spent the last few years living on a steady diet of boar and fruit and beer and probably meth, idk he's generally just a grubby gross thug.

Extremely unstable, mercurial, and prone to sudden, unexpected bursts of rage. Sadistic. Psychopathic. Considers himself completely sane in an insane world. Regularly takes extreme and potentially deadly risks without any sign of hesitation or fear for his own safety. Don't talk about his sister, and definitely don't fuck his sister. Jason.

Fine! Drop me a line so I can tell you what your character would see. It's gonna be bad shit, amigo. It also carries the risk of referencing psychological abuse and extremely dubious brother-sister incest from a victim pov, so lmk if you'd rather swerve mention of that.

Don't talk about his sister, don't talk about Jason Brody, and probably don't bring up the concept of family either (he's got Issues with it). He dislikes disrespect that isn't entertaining or drags out to the point of not being funny anymore, pleading/screaming/begging, and minor acts of defiance in his captives, although he's less likely to get violent with those! He'll just call you a pussy.

Also, try not to point out how insane he is. He doesn't appreciate it.
