Au-Sin

The biological cousin that moreso performs or holds the role of an Aunt than a cousin to you.

Comes from the blending of Aunt + Cousin (Au from Aunt + Sin from Cousin)

Originates from the Midwest USA in 2020.

Hey, my Au-Sin is going to drop us off at the salon. Who? My cousin, but she's old enough to be my Aunt.

Cock au two

Flying "The Bird" (middle finger) with both hands at someone acting in a manner of dickishness.

My "cock au two" rose to the occasion when Vince decided to ditch out on the group during last night's pub crawl.

Aus Stre

A liar, especially one who lies about going places, getting drunk, and about being old even though they are 16 years old.

Guy 1: This guy on the internet says he’s 25 and has gone to so many events in Baltimore in the last 20 years!
Guy 2: nah he’s an Aus Stre. Look at his old channel and Roblox account. The proof is that there.
