Headstop
The act of going down on a penis (blow job) only far enough to take the head into your mouth.
Last night that bitch Dara would only give me the headstop, so it took me 30 minutes to get off!
Headstop
Only sticking the knob of a weiner in your mouth
That horny girl dara really needs to stop doing the headstop and stick my whole man meat in her mouth & throat
Headstop
The act of grabbing on to her ears to stop her from giving you head, as to move on to better things.
I had to use the "Headstop" maneuver on her so her girl friend could have a chance.
