adjective. Used to describe something that is funny. see jokes
This originates from the Home Counties of the UK, more specifically from the St.Albans area, and is formed by replacing the ending of the word jokes
with the sound made popular by snoop dogg, "izzle", thus creating "jizzle". The reasons for doing this are unclear but may be due to a need in the white suburbia of the home counties to sound more gangster, hence the "izzle".
But also may be due to the humorous similarity the word has with another word jizz
, which means spunk.
