In the game Counter Strike Source, a counter terrorist is skum (worthless garbage that needs to be humiliated and sliced into little pieces with a knife).

A cultural and aesthetic mind-state that prioritizes making money, even as an “underground” or “radical” creator. The work isn’t made for money, but it’s the money that matters the most.

Skum is when you're so high that you can't think straight. That's basically it.

Of or relating to the group of bmx'ers characterized by greasy hair, shitty attitudes, often missing front two teeth, in times poor education and grammar, and are more commonly found residing in Arizona. Can also refer to something as being "skummy."

Adjective used to describe a creature as a awkwardly blossomous positive contributed to a squad or kick line team. Great sense of humour and taste in clothing. Enjoys 5sos and flannels. Daddy kink. Christmas AF. Not to be confused with scum
