Midget Macarena
when you see a midget, it is common courtesy to publicly identify the said midget, either verbally or physically, and subsequently perform the macarena. failure to do so will result in your spouse fornicating with a beloved relative.
ex: yo, is that kid a midget? *points at the midget* i have to do the midget macarena now, or else my bf might cheat on me with my brother!
