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."

grandfather clock

While mooning someone, the mooner bends over exposing his dick and balls. He then sways back and fourth as to make his dick look like the long pendulum on a grandfather clock

It just started as a casual moon, but then turned into a grandfather clock

Grandfather-Clock

When one gets on a table without your pants on, and swing your junk left to right.

I did a Grandfather-Clock to your mom

Grandfather

The person who turns you into a man and makes sure you aren't in bad health.

My grandfather is the older version of a badass role model who won't take shit from anybody.

grandfather cock

When you're trying to shop for some antique grandfather clocks for your paps but then you unfortunately forget the "l" in "grandfather clock" and now you wish you were dead.

Poor Fool: *mistakenly types 'grandfather cock', clicks on 'images'*
*questionable things appear*
Poor Fool: AH DEAR GOD GET THE BLEACH
