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...
A shirt in which the sleeves are too big for the individual wearing the shirt and cover the elbows - a synonym to 'shants' (shorts/pants). The word 'slong' is a conjunction of the words short and long hence slong: not to be confused with a large penis-sleeved shirt, though hilarious. Slong-sleeved shirts are usually worn by the over 40, which is generally excusable, but under this age, slong-sleeved shirts are not acceptable. Not to be confused with three-quarter shirts.
A long sleeve party shirt is a crop top or cleavage exposing shirt, that is worn in the wintertime and obviously has long sleeves. It is a shirt that is slutty, but looks warm too!
A Short-Sleeved Genius is a person, usually a male, who abuses their minor managerial role within a business setting. This person utilizes their limited power to assert complete authority or assumed knowledge in an aggressive manner. Think a psycho Pep Boys manager or Dwight from The Office. While anyone wearing short sleeves and a tie is a potential Short-Sleeved Genius, it is not a mandatory dress code.
I was at the DMV getting my license renewed when some Short-Sleeved Genius told me I was in the wrong line. He threatened to "write me up" if I didn't change lines. WTF, I don't even work there!
Someone who runs from indoor location to indoor location due to the fact they're wearing a t-shirt in sub-zero weather.
This is a Canadian phenomenon that tends to occur in spring and fall. Due to uncertainty of the weather and the fact most Canadians like to act immune to cold, The Short Sleeve Hustle is often witnessed.
