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.

T-shirt training refers to going to the gym with the sole purpose of gettin' buff for da ladiezzzzz. Often performed before a big night out in order to look fresh, a t-shirt training session involves doing bench press, biceps curls and tricep extensions in order to get PUMPED!!!!!!! Although such a routine will leave you with a disproportionate upper body half, this is not an issue as massive 'guns' are DENCHHHHH!!!!
It is a well know fact that if you perform a big t-shirt sesh before a night out, you are 99.99% more likely to get laid.

per the ex mayor of NYC, when lying on the bed waiting for a blowjob, but caught with your hands in your pants, your excuse is "tucking in my shirt"
I was tucking in my shirt, after taking off the recording equipment (but before she took her clothes off)

When an individual's man-boobs/boobs and large gut cause a shirt being worn to take the shape of mickey mouse's head and ears.
