Originated in early to mid-90's in Queens, NYC. Brought to web by Kaedaq in the late 90's

Thun is a version of the slang term "son". Was born in 93 when Queens residents started to pronounce words that began with the letter "S" with the "Th" sound instead, thus giving it a lispy sound.

Contrary to some belief, it is NOT a form of the word "thug".
