jackassume 

To make a very idiotic, or "jackass" assumption. Concatenation of the words "jackass" and "assume"

GF: Don't think you can hide yourself from me. I know that you're checking out that girl who you think is better looking than I am.
Me: Just because I'm looking at that girl doesn't automatically mean I'm checking her out. Maybe I just want to see if she's one of my classmates at my previous school. Maybe I'm not looking at her, but rather, the traffic that's behind her. Don't jackassume things.

Jackassperger's 

An affliction presenting with many of the same symptoms as traditional Asperger’s, but with the obnoxious and asshole markers turned up to 11.

While Kyle is wicked smart and a bit socially awkward, he’s really kind of a douche at the same time. I’m pretty sure he suffers from Jackassperger's. Sadly, there is no cure and we’re going to have to put him down.
