Yellow Mellow

Urine that is left to settle in a toilet bowl. Comes from the energy saving saying that goes "if its yellow, let it mellow. if its brown, flush it down."

Not to be confused with Mellow Yellow which was a song by Donovan in the 60's composed when he took the drug Mellow Yellow. Also not to be confused with the drink popularized by Coca Cola.

"Stop leaving yellow mellow in the toilet! The dog drank out of it and licked my face!"

yellow fever 

1) A disease carried by mosquitoes in tropical regions, especially in South America, Africa, and the Caribbean. Symptoms include sudden fever, yellowing of the skin, and hemorrhaging. A very dangerous disease that is quite often fatal. It was the number one cause of death for Americans during the construction of the Panama Canal. Nowadays a yellow fever vaccine is required if you're traveling to said tropical regions, especially during the summer.

2) When a person of non-Asian ethnicity has strong feelings and/or urges of an Asian person of the opposite gender. Usually these urges are sexual, but not always. Wasn't too widely known until the release of Harold and Kumar Go to White Castle.

1) Good God that vaccine hurt! But I guess it's better than dying....

2) Little Billy went to a club in Chinatown and now has a sudden case of yellow fever.
