A shart (a fart accompanied by some liquid poo) exploding from the anus following the consumption of greasy fast food such as Mcdonald's, Long John Silver's, or Kentucky Fried Chicken.

Get the McHattie mug.The act of holding your straw like a knife and then shanking your buddy's large McDonald's cup on the side in an attempt to make a huge mess. This only works with the large cup since it's the only one made out of styrofoam .
Leo (thinking): I should McShank Hans just because i'm bored....
*Leo then McShanks Hans' large cup*
Hans: Hey man! WTF! you ruined my cup and made a mess!!!
Leo: How You Like Me NOW!!!
