The look a guy gets on his face while masturbating. Most males get a jerk smirk on their face because of the uncontrollable pleasure they are feeling. A jerk smirk can last for several minutes after a guy ejaculates.
Duder 1: "Hurry up in there dude, I gotta trim my bush."
Duder 2: (comes out of bathroom) "Sorry dude, it's all yours."
Duder 1: "What the hell is that jerk smirk on your face for? Awww dude if I step on any of your nasty ass cum..."
(v.) to roll one's eyes whilst concurrently simulating (male) masturbation , used whenever one encounters absolute douche-baggery or ridiculous-ness.
"I was TOTALLY pulling a smirk-and-jerk as my ex was telling me over the phone how he didn't miss me at all when my phone's missed call log proved otherwise."
To avoid doing work while on the clock whilst taking care of one's needs. Less euphemistically: to jack off at work.
I was feeling really stressed at work today, so I locked my office and closed the blinds for a good ol' shirk and jerk to relieve my tension before the board meeting. Totally killed the presentation!
Someone who jumps from one relationship immediately into another one.
Serial monogamists can not stand to be alone and often suffer from vast commitment and insecurity issues.
Because they jump into relationships immediately after the previous one has ended, serial monogamists typically don't take the time to reflect on their behavior or why their previous relationships failed; thus, they end up making the same relationship mistakes over and over again.
Person 1: Damn, Dustin already has a new girlfriend?! It's only been two weeks since he broke up with his fiance! I think he's a sociopath.
