Excessive Jager-like behavior. This includes sitting on the bed of females while they shower, watching other men while they sleep, getting a ton of food and eating half of it, and explaining of a procedure involving the relocation from the glutius maximus to the abdominal to sporting coaches.

Bultman had to teach Zack a lesson after the trip to the alley didn't stop him from jaggin' out.

Jigglin' out 

The act of masterbating so hard that your legs give out.

Tommy was jigglin' out so hard that he fell flat on his face.
