When your cock is so enormous that a chick can only fit the head inside of her as she tries to ride you, and you can then have some fun by spinning her around on it like a barstool.
This bitch was so too tight to fuck properly, so I decided to give her a spin on the ol' Bar Stool.

A particularly large, fiberous shit that you fear may approach the standard 24 to 30 inch height (and possibly require a c-section).
I could hear Chad screaming in agony as he constructed a massive barstool in the handicapped stall earlier. It sounded like he was in labor!
