nothing sluttier than lighting up a cigarette immediately after an absolutely brutal fight and inhaling deeply before exhaling the smoke with a sigh of relief while still disheveled and covered in blood and coming down from the adrenaline high. you could literally have sex onscreen and it would be less erotic.
and getting someone else to light the cigarette for you because you're too badly injured/exhausted to do it yourself... that's gay sex baby
bonus points if the person who lights your cig is the person you were fighting and they ended up just as fucked up as you are
