1. Referring to a tank top. Usually a
men's tank top. Not to be confused with a cutoff
shirt. Though both serve the same purpose and are equally as comfortable, a cutoff shirt is not a tanky.
2. An eloquent
way of mentioning a tank top without having the harsh sounding words, "tank top", sticking out in your sentence and sounding like a douche.
Example 1: "Man, that's a pretty sweet tanky. Where'd you get it?"
Example 2: "A tanky is the best kind of
shirt you could wear to work out in."
Example 3: "It's so hot out here! I
wish I had put on a tanky before I
left my house."
