slow jerk

A phrase used when something turns you off. Instead of being able to quickly beat it, your jerk gets slowed down because of a stupid comment or disgusting premise. Akin to an "eye roll" and often accompanied by a slow, masturbatory gesture.

Girlfriend: "We should totally see the Nutcracker when it comes to town!"

Me: "Ugh, slow jerk"
