I saw the weegie and immediately googled (curiosity killed the cat).
1. (n) A slang term for a person from Glasgow. Sometime used in a derogatory manner.
2. (proper N.) An internet nickname referring to Luigi of Super Mario Bros Fame.
3. (n) A mispronunciation of Ouija, as in "Weegie Board".
I guessed number 1 was referenced but I couldn't resist finding something stupid with the number 2 explanation
