When a male has a cock that is at least 4 times bigger than the average cock. MEGAMEATS are a hassle to walk with due to their length and weight, so your best friend has to carry it around. MEAT refers to the cock, MEGA refers to the size.
William, my MEGAMEAT itches, will you do me a favor and itch it for me?
