Get the foo mug.
a slang abbreviation for the word "fool". May have originated with black people but people of nearly all ethnic groups use it now.
1. Mr. T often says "I pity the fool". The last word in that phrase has often been mistrued as "foo".

2. In my sociology class in college our professor was giving a presentation about the presence of violence in human society. He stated that the family is the 3rd most "violent" institution in society (#1 and #2 being the military and police due to what said occupations may require). He mentioned domestic abuse and soon he drifted direction to the women, talking about date abuse. He said "in a relationship no one should be calling all the shots. If you don't want to do something he shouldn't try to force you to. If he ever beats you THEN THE RELATIONSHIP SHOULD BE OVER. If he does it once he'll do it again. He might say that he can change but he won't. People like that want someone to control and use. YOU DON'T HAVE TO TAKE IT FROM THE FOO. You deserve better. You need a real man, not some immature foo looking for a punching bag or someone to slap around..."

3. to a certain Bahamian celebrity: are you reading this? We saw that picture and what some foo did to you. Don't be a foo too!
