My sisters and I make up funny words and nicknames for eachother. Eeeverything is a joke. The other day Erica and I were walking around Chinatown repeating "geez, banana, shut your freaking gob!" as loud as we could. We do a lot of movie and tv quoting. When it's just us girls we get really loud and obnoxious an it doesn't matter if it's in a grocery store or the dinner table, nothing is off limits.
