Glasses-On-Butt

The G rated phrase used to call someone a smart ass.

Parents, my kids & I saw alert on highway about 2 escaped prisoners.

Mom asks "where did they escape from?"

I reply "from prison"

Mom says "thanks for stating the obvious glasses-on-butt"

glass of butt

When you are thirsty for that ass so you ask for a glass of it.

Damn kid, did you see that ass? I could use a nice glass of butt right about now.
