Pre-break-up 

When you break-up with someone before a relationship even starts.

I was talking to a guy and after I saw we weren't compatible we decided to pre-break-up.

Pre-bound

When someone cheats on their significant other right before breaking up with them. Easing the transition into single life, and setting the stage for a rebound.

Molly was unhappy with her boyfriend Tommy for years. She slept with Johnny right before dumping Tommy. This helped bridge her gap (pun intended) into single life. she can now rebound off all of Johnny’s friends. “ hey John thanks for being her pre-bound, now I’m her rebound”.

Pre-ex 

Pre-ex refers to your ex boyfriend/girlfriend before the break up. Many people get confused when someone refers to their ex if they are talking about before or after the break up.

If a person says, "My ex burned my house down" you wouldn't know if the ex boyfriend/girlfriend burned the house down while they were still dating and that's why they broke up or if they broke up and then the ex boyfriend/girlfriend burned the house down.

Bro 1: Bro I made out with my Pre-ex a lot.
Bro 2: Nice, so who you making out with now?

Pre-existing condition 

An old flame you can’t help hooking up with periodically, regardless of either person’s relationship status.

Amy: I can’t believe you slept with Adam after the class reunion. He’s engaged and you have a boyfriend!

Lola: Hey it wasn’t my fault. Adam is a pre-existing condition.

pre-cough swallow

Refers to where you feel a cough coming on while your mouth is full of food/drink, and so you hastily down the entire mouthful so that your mouth and throat will be free to expel the cough "cleanly", rather than there being a humongous "geyser" of messy stuff to go flying all over the place and disgustingly splattering everything within a several-foot radius.

I'd just swallowed a big bite of spicy-hot chili and was in the process of washing it down with a swig of cold milk when I felt an overpowering urge to choke, so I did a hasty pre-cough swallow to avoid a spluttery shower of tomato-tinted milk all over my new tablecloth.
