Mystery bags 

Sausages. So called because who knows what is inside. Sometimes meat. (Rare)

I had a couple of mystery bags with sauce for lunch. At least I kept the sauce down.

mystery wind 

The unexplainable, but rather enjoyable rush of wind that is emitted up the stairwells leading to the subway system.

Christ it's hot outside; that mystery wind really does hit the spot.

mystery woman skill

A mystery woman skill (term coined by tiktok user @kartere) is a sort of unpredicted and cryptic skill, like being good at identifying plants and flowers, speaking latin, belly dancing, or anything else with that kind of vibe.

My mystery woman skills are playing the harmonica, imitating bird song, and in-depth knowledge about greek mythology.

mystery plug

The act of "accidentally" slipping an ecstasy, or thizz pill onto one's ass during anal sex. One would place a thizz pill against the receiver's asshole without the other knowing, then immediately after- shove his dick, or finger, in this persons anus hole. This requires precision and a loose ass, or a lot of lube. Can be used on a guy or a girl, or a cat. Whatever you like to fuck will be surpised when the sex feels better than middlefuck's tongue in ur ass.

I'm gunna pull a mystery plug on Mario because I want him to let me rail his bungsnacks all night.

Flip is thizzin because I mystery plugged his asshole.
