A man who excessively masturbates, to the point where his penis has grown in length exponentially, due to the number of times he has jacked off.

someone in 3rd grade who steals all of the red crayons and markers. A blue jacker is someone in 6th grade who steals your blue.
Hailey: I like red, I'm gonna pick up the crayon and color with it
Dominic: Dude that red is mine (takes red)
Hailey: Dud you are such a red jacker
Dominic: Dude that red is mine (takes red)

When some doosh (usually named Blake) jacks a beat (electronic focused dance music) that has been discovered by you.
"Dude Blake just played me the dopest beat, its a Designer Drugs remix of Countdown" Blake jacked this beat from you making him a beat jacker.

Eating Black Jack sweets before giving your bf a blow job then as he cums, choke on his jizz and puke the black jack and jizz mixture back up on his dick!
'Oh hey Zac! I did a black jacker on my bf'
'What's that then Emma?'
'Well I ate black jacks before giving my bf a blow job and I puked on him as he cum in my mouth..'

One (male) who in conversation with a fellow, workmate etc is inclined to grab the other guy's crotch suddenly and without warning. The object is ostensibly to put the victim ill at ease and in a state of embarrassment. However, one wonders if it's simply an excuse to grab other mens' genitals.
Tony: I hate talking to Mike. I'm in the middle of a sentence and he just grabs my dick every time
Stan: yup, he's a cock jacker to be sure
