1) A brain disease where you suck at every aspect of life, especially videogames; caused by head trauma at a young age; e.g. your mommy dropped you on your head when you were a baby
2) When your all out feminine side is blatantly present and you are, in essence, a faggot
3) A disease where one frequently engages in faggotry, taking dicks up the butthole quite often
