This is a question for men (age 18-25ish) who've been with women. What does it mean when you bight your fist in regard to a woman. Here's the story, i woke up last night to find my roomate in bed with an extremely hot woman. not sure if they had sex, but when he got up the next night and she walked into the bathroom. he looked at me and smiled and bit his fist (as some sort of signal to me or something ) and I'm just wondering what that means? maybe it meant that they had sex? maybe it meant she sucked good dick? well right now its about 9 am and they were making out on the bed so i had to get out of there. i'm sitting in the lounge with my macbook. Anyways, is fist biting some sort of sign betwixt heterosexual men?
