Nice term to describe anyone designated or willing to stay sober at events involving alcoholic consumption. Basically, a nice way of saying, "don't worry my friend, I'm staying sober- so you don't have to! Which means I'll be there at the end of the evening to question that 'date' you picked up, drive you home, and provide adequate support for you're drunken heap of a body... well go on then, get drinking!"
Joseph: Hey, you having a drink?
Joe: Nope, I'm staying sober- so you dont have to!
Joseph: okay- You just volunteered to pay... bitch!
Making ones self almost ejaculate but completely stopping just before you actually climax. Wait 20-30 seconds and continue. Perform this process 4-12 times for maximum pleasure and then when one finally ejaculates, the nut has an incredible mass.
This process is usually performed during wanking but can be adapted in sexual inter course.
