XXX - Boyfriend Nicknames

Three girls were discussing the nicknames they have for their boyfriends..

 

The first girl says, "I call my boyfriend 'Mountain Dew', cause he always wants to mount and dew me".

 

The second girl says "I call my boyfriend 'Seven up', cause he's got seven inches and it's always up".

 

The third girl says, "I call my boyfriend 'Jack Daniels'".

 

The other two girls were stumped for a moment. 

 

The second girl piped up, "Isn't that's a hard liquor?!"
