Basket-stall 

The act of throwing a wad of toilet paper or a paper towel ball into the stall being used by someone who is releasing quite a foul and pervasive smell during his or her bodily process of defecation and while preventing that person from knowing that you were the one who threw it. Can be played by one person or numerous people using the restroom upset by the vile odor.

Jack was stinking up the restroom again, so Dave and I played a round of Basket-stall. I stole the ball made a lay-up it into Jack's stall. Shortly after our victory, we ran off like pussies and laughed our asses off.

Courtesy Stall 

The act in which a man using a public restroom will seperate himself by at least one stall as a courtesy to another man that is already established at a separate stall. This can be done either at a urinal or a traditional stall.

I walked into the bathroom and noticed that of the three urinals available, a man was occupying the one on the far left. I gave him a courtesy stall and went to the urinal on the far right as not to appear gay.

Larry Craig Stall 

The empty stall between two men taking a dump. Ensures neither man questions the other's sexual orientation because someone's foot seems to be a little too close to the other stall.

Similar to the I'm not gay seat in movie theaters or the I'm not gay urinal.

Named after the Senator, Larry Craig, who was accused of trying to arrange a homosexual rendevous with an undercover cop by tapping his foot under the side of a bathroom stall.

I just got back from the bathroom, the empty stall between me and the guy who came in after me was the Larry Craig stall.

There were only 3 stalls and the 2 end ones were occupied, so I had to use the Larry Craig stall.

Two Stall Rule 

Also known as the two urinal rule. In a mens' bathroom with a row of urinals, whenever someone is using a urinal, the next man to come in and use a urinal will go at least 2 stalls down (ie, you are at stall zero, the one beside you is stall one, the next one is stall two). Whenever someone violates the two stall rule, the person who is violated feels uncomfortable, even if it is the violator's best friend.

Sinks count as stalls as well.

Man, he just violated the two stall rule by pissing next to me!
