so my sister went to a rave the other day. i looked her up on facebook this morning (overprotective big brother) and a guy she obviously met at the rave is like "hey bff ahahah i just read what you put yourself down as on my phone.. it says "asdfasdf your bff " whats up?" my sister is 20 if that matters. what do you guys think? this whole bff thing is pretty common right now in my age group (18-22). at parties i often see girls call guys bff that they just met while playing beerpong together or soemthing. anyways, just wanted your guy's input. i hate the idea of people gaming my sister rofl.
