an (insert number between 1-10 here)

a way to describe how attractive someone or something is by rating it on a scale of one to ten where 1 being a fucking pig and ten being a extremely hot man or women (usually a woman in most cases).

"How hot do you think that girl is?"
"I would say an (insert number between 1-10 here)."

-1 out of 10

Something so bad, a 0 out of 10 is being generous to it.

"I rate Cats a -1 out of 10"
