Top definition
A test of objective internet authenticity where the person being sequestered is asked to take a photo of him or herself wearing a green shirt with/in front of/near the object in question.

Originated from the Mugen parts topic of the worlds largest Honda enthusiast forum, this was first used to prove the authenticity of a Honda del Sol Mugen front bumper cover.
Memphis: Hey I own a jet ski!
Vega: Prove it!
Memphis: How?
Vega: By taking the green long sleeve shirt test!
Memphis: What's that?
Vega: Take a picture of yourself while you are eating a jelly dough-nut next to your jet ski pointing at it while you hold a calendar with my birth-date circled, and you must be wearing a green long sleeve shirt...
