tweating off 

Tweeting to all of your friends and fans that you are masturbating, while masturbating. (male version)

I like tweating off to late night infomercials because nothing is sexier than watching a past-her-prime actress try to sell a $2 piece of junk for $19.95 and having your friends know what you like to do while alone.

Tweezing-off 

The act of masturbating with a a pair of tweezers, due to having a small penis.

I was up late last night and I heard my friend tweezing-off. I could tell because i heard the sounds of moaning and metal clicking together
