1) One who masturbates excessively; He who "jacks off,"
"chokes the chicken." Someone who "services themselves" on the daily more than an Oil Can Henry's!
2) Can also be know as a horny "Guy" who you're sure of him "rubbing one out" like its clock work and he's being paid to do it!
Peter: "Fuck!! I woke up so hungover, I just jacked off about 5 times this morning!"
Frank: " Fuck! Pulling another Jerry Jerkmans today or what?!!"
