a shortened form of the word "legitimate". however, this term is nowhere near the real meaning of "legitimate", since it is commonly used to describe things as cool or extremely awesome.

Short for "legitimate". NOT short for "legitimately" which is a totally different word. The difference is roughly the same as between "good" and "well" – in case you cared. An extremely popular yet badly understood filler word.

Sparky: "IKR? He could've been literally one of the greatest, though."
