What is 31st Base?
oral sex performed over the phone where the guy sticks his dick in the phone and it comes out the other line into the chicks mouth. just like the cartoons, the real definition of phone sex
chick #1: i was talking to my bf the other night and before i knew it i found his dick in my mouth
chick #2: i hate it when those fucking telemarketers get the better of me
guy #1: 31st base is the new form of cyber bullying
