Uugh, look at that squill parking his Lambo in the bike lane.

This fucking squill bought herself a Gucci handbag last week and gave $5 to my GoFundMe for insulin.

My landlord raised the rent again but they still wont fix the leaky roof. What a squill!

someone
who
isn't
me

commonly used to avoid self incrimination in contexts such as boards discussing drug use. also used in places where generally criminal acts are taking place. (not dissimilar to use of illicit drugs)

m is sometimes replaced with y (for you) wherein someone would be questioning another.
swim generally prefers mainlining to fix himself. also, how much does swiy pay a day to support his habit?
