An insult meant for describing someone that is both bitchy and fat giving them the look of the Michelin man with major PMS! This person can be male or female. This person can also have or not have a menstrual cycle.
Someone should have told you that you can't become less bitchelin by watching P90X seated while you drink a hundred and one Dr. Peppers a day!
The name of a four year old boys biceps.
While yelling excitedly at his mom and flexing both upper arm muscles at once the boy says, "check out these fuzzies, I'm strong! Grrrrrrr..." The mama bear just giggled and agreed with her little cub.
