Fit thic

A bountiful booty that is carved from the grindstone of the gym

My girl hits the gym so hard she fit thicc. That booty be poppin squats erryday.

skitey

Slippery. A dodgy person

Common in Scotland.

"He's a skitey wee thing." "Serves you right for being skitey". "I don't wish to sound skitey, but ..." "She is a skitey eyed cow."

In the context of the weather, in place of slippery, you might say "watch out outside, its a bit skitey".
