Someone you contact for a good ol’ fashioned dick down (I.e boy toy). More of a benefits situation than a FWB. You can count on this person to come thru upon summoning and they are equally aware of their role.
A: What are you doing for that date later?
B: It’s not a date, he’s coming over tonight to watch Netflix so I have him down as a dick plug.
When a man has intercourse with a woman with a butt plug in, ejaculates in her, pulls the butt plug from her, then puts the butt plug in her vagina
"The other night the missus and I were having trouble keeping the cum in, so we tried the Cream Plug"
Akin to smeg, which forms on the foreskin of the penis, plug shit is a cheesy, foul smelling substance that forms on the jewelry worn by those with stretched lobes (called gauges by 14 year olds who shop at Hot Topic). Plug shit itself is a mixture of sweat and dead skin cells.
I took out my plugs the other day, and there was a ton of plug shit on them.
