Used to describe something very slippery and/or slimy, like a "minnows dick"

Well I'll be damned, that tire's slicker than a minners dick!

don’t tread on me

Could either refer to the 1991 song by American band Metallica or could refer to a flag popular among Republican Americans, in which the flag is a reference to said 1991 song by American band Metallica

“Bro, I love Metallica’s song ‘Don’t Tread On Me’”
“Don’t tread on me pal, you’ll be regretting it”
