8. Lil Wayne - How To Hate (2011)
Which lyrics? "But dont f**k up with Wayne cause when it Waynes it pours!"
Why? What a complete and utter prat this man is! So many of his lyrics could make this list, but this one takes the biscuit. This particular single features his buddy T-Pain, but it is typically a Lil Wayne effort that shines above all else on the stupid scale. In what might be the worst pun in the history of puns, Lil Wayne issues a threat not to "f**k up" with him because when it "Waynes" it pours. Get it? Like "when it rains it pours"? "Genius" (and for that read "idiot"). http://www.youtube.com/watch?v=CdMk_ySjcAE
