masturhating

The equivalent of a cock block, but when it happens during solo masturbation. Someone knocking on the door while a man is jacking off inside would be masturhating.

Jon: So what'd you do yesterday man?
Alex: I was bored as shit so I was just jacking off until my brother knocked on the door. Totally masturhating.

Masterdating 

When a person (typically a guy) goes out to see a movie, or visits a theme park, or place otherwise mostly occupied by couples or friends,but does this alone. This can cause sympathy from other people that watch them as they purchase tickets or enter the area. This is different from when a person grabs a cup of coffee, or sits in a coffee shop alone for a few minutes, or rents a movie, or eats fast food. Masterdating involves often going to a restaurant alone, and sitting at the table alone, while some people look and either feel bad, or think that the person is a looser, or going to see a movie alone. It is often done by older men that may be widowed, or by people that can't get a girlfriend, or are the "40 year old virgin" type

You: 4 tickets for (name of movie) please
Masterdater behind you: 1 ticket for (name of movie) please

You (thinking) awe, he's alone, i guess he's Masterdating.
