Where one's testicles hang so low that they swing between its owner's two legs like the pendulum of a grandfather clock.

Your Grandfather a Shlother 

Even worse than Your granny tranny and your dad lesbian combined. Whenever used, it will end a planets life of any choice it chooses.

Kris: Pass me the chips or your mom gay
Shally: No get it yourself. Your dad lesbian and your granny tranny combined.
Kris: Your Grandfather a Shlother.
Shally: *explodes along with another planet into the depths of space*

stairway in a grandfather clock 

A total upset. One of the biggest surprises you've seen in a long time. Like discovering Ma'am and George had a secret passage to upstairs for Webster, hidden away inside a faux grandfather clock.

"Wait a second. So you're telling me Ivy is a dude???"

"I slid off her pants and...fuck. I think I'm going to be sick again."

"She didn't have a bulge or anything?"

"Nope. Like a fucking stairway in a grandfather clock...ugh...I'm going to hurl again."
