Vanderwalling 

Vanderwalling is when a member of the Highly intelligent (no sarcasm) Vanderwall family has the urge to fight. Usually for no reason other than their own inner turmoil. When someone is Vanderwalling, they are partaking in long drawn out verbal altercations (these are the best kind, especially on social media) picking physical fights that they always win, or just being mean and degrading to those around them. These conflicts are often filled with witt, Clever descriptive words, accurate and hilarious observations. Vanderwalls are thoroughly entertaining, but ruthless and extremely damaging to their target (s)

1: Dude, why is she being so mean?
Oh, she's Vanderwalling because she had a rough week.

2: I can't handle all of these emotions. I need to go somewhere and do some Vanderwalling.

Vanderwallen Squeegee 

The act of emptying out a used condom so that it can be re-worn by a second male, usually for use on the same woman.

Example #1 Tyler and Jeremy didn't have enough rubbers to both do her, so they pulled a Vanderwallen Squeegee.

Example #2 Pulling a Vanderwallen Squeegee is still safer than going bareback when you're tagging a cougar.
