Another name for girls who are packing a little extra poundage.
Derives from Playboy, where the women are called "bunnies". Therefore, a larger girl is referred to as a "chubby bunny"
Note: Playboy does not refer to slightly overweight women as "chubby bunnies"
Kevin: Hey, look at that golf cart.
Sean: Yea, that's the one with the chubby bunnies in it.
