When you do nothing but jack off and eat all day. Not necessarily in that order. Usually associated with a porn addiction.
I never see John any more. Has he been working a lot? Working? The guy's a rub and grub. He never leaves the house and he pays for his porn accounts with his food stamp money.
Marathon jerk off sessions. Repeatedly jerking off followed by eating.
I have an 8 Hour online porn pass. Rub n grub for me today braaaahhhhh.
