Three girls all had boyfriends with the same name, so in order to avoid confusion, they decided to give the boys nicknames.
The first girl said: "I call my man 7-Up."
"Why do you call him that?", asked her friends.
"Because he’s seven inches long and is always up."
The second girl said: "I call my man Mountain Dew."
"Why do you call him that?", said the other two.
"Because he likes to mount and do me!"
The third girl said: "I call my man Jack Daniels."
The others look at her in bewilderment and say: "Why do you call your man that? Jack Daniels is a hard liquor."
