Swinging door.

Another way to say you're bisexual. To be bisexual. To play for both sides. To date both men and women. To have sex with both men and women.

- "Is he gay?"
- "No, I think he's just a swinging door."
- "Excellent, I have a chance!"

lock-door bathroom

A bathroom with a door that locks. These bathrooms are not meant to contain more than one person in them at a time. Even if one person is only washing his/her hands it is considered taboo to enter a lock-door bathroom.

Commonly found in convenience stores, and fast food restaurants where space is limited. These can be found in a variety of modus operandi including, but not limited to, unisex, and handicapped.

"Brandon, don't go in that bathroom. It's a lock-door bathroom and someone is already using it. You don't 2-person in a lock-door bathroom."

diamond doorknob

before you give a guy a blowjob you fill your mouth with champagne and blow it up the guy's asshole. he needs to clench his asshole while you give him a blowjob, then when he cums he shits. the champagne enema makes the feces all hard and sparkly, like a diamond doorknob.

damn, allie just wasted half a bottle of Dom giving that bro a diamond doorknob!

hippopotamus doorknob

Noun. A process in which a person shoves an umbrella in his or her anus, and then promptly opens it up, thus making his or her asshole larger. The misguided soul then proceeds to put watermelon-sized anal beads into his or her rectum. This being must then try to regurgitate these objects into a friend's mouth. Finally, the friend runs to the nearest zoo naked and gets impaled by a rhinoceros.

- Damn son, why you so stressed today? Did ya take a hippopotamus doorknob recently?
- Yes, my anus is still sore.
- I'm sorry for your loss.
