costume parties are wicked! puts a spin on it plus it makes it easier talking to people ya dont know. then when ya meet them a few days later your still talking about the funny costume they were dressed as.
for my 21st i had a theme of 'Stereotypes' and it was madd! everyone got dressed up and got into it! had a few other so called 'games' that were based on stereotypes where we had your typical prom king and queen dance where the best costume by a girl and guy had to dance afterwards and shit like that. my mate took the title literally and came as an actual stereo type which he labelled 'Skinatron' (his nick name is skinny)
there fucken madd fun and i wish more of my mates did costume parties. just hard sometimes when you find out about it a bit to late and its hard to get something together.
