Slang Of The Day

five minute foot long: a term used to describe a man that has a massive penis, but lacks the skill to use it to its full potential

Used in a sentence:

Sarah is having a bad day she slept with Lance last night and discovered he is a five minute foot long.

I became aware of this conversational gem, at my new favorite website:  http://www.textsfromlastnight.com/ 

Beware, its highly addictive.
