When two girls or guys find out that the same person ejaculated inside them. Because of this common bond, they become best friends.

They are probably one of your best friends and someone you can tell anything to and trust with your life. They are the person that would do anything for you and always keeps you strong and is kinda like your battle buddy (meaning whatever you do/go that's what they're gonna do also). Your 'Shot Buddy' ultimately is most of all the person who won't let you drink alone (because that's just sad) and will always be there to look at you and say "If you take it I will".
Becky saw Zack taking shots by himself at a party so she went and took them with him, they became shot buddies and now bestfriends.

A friend who doesn't get high, but comes along so when you get high, they can watch your back and you don't do anything stupid. Also they can supply entertainment that makes sense, because they're not high. And they get the food when you get the munchies.

A Variation on the traditional bunk buddy sleeping arrangement in male bedrooms. Rather than have separate bunks for sleeping, the top bunk is used solely for masturbating with the bottom configured for top n' tail sleeping.
Looking Forward to going skiing next month, Karl has agreed to be my Spunk Buddy for the week. Saves fighting over who gets the bottom bunk !
