1 definition by Kate the Grammar Vandal
A flabby upper arm that jiggles when you raise it and move it around, not unlike the arm of an overweight senior citizen who spends all her free time frantically waving her hand at the bingo table.
"Don't wave while wearing a short-sleeved shirt or people will see that you have a bad case of bingo arm."
