Get the Grandmamug. Verb. To grandma another person is to jab them on their side right below the ribs, while saying GRANDMA. The goal of a grandma is to demean the person receiving it and make them feel uncomfortable.
Yo Steve, you're so brown. Get out of the country.
GRANDMA! (performs the Grandma)
AHH YOU MOTHERFUCKER!
