Is a term used in prison to describe contraband (ie. drugs/lighters/matches) which usually are smuggled in some body orifice of the human body (ie. virgina/anus). The contraband typically is wrapped tightly in a elongated shape with plastic wrap first then wrapped in black electrical tape. Some sort of lubricant may or may not be used to ease the insertion of the slug into the orifice.
1. I got a slug in me that's so big it made my ass bleed.
2. I caught a inmate unwrapping his/her slug that was full of pills, pot, and wrapping papers.

After a heavy rain, the backyard became a treacherous terrain, and my shoe inadvertently encountered a mud slug.

Devoid of the necessary emotional or artistic mobility to make the slightest impact despite all efforts, if any.
Those songs sucked the first time around, you expect people to pay a cover to listen to the same slug-lame arrangement of all of them, back-to-back, for three hours?
