An evil machine device which pushes up ones weapons of mass pleasure to a high level, encouraging you to take off the bra before they pop out and so you can touch em, but the evil thing prevents you from getting to the boobies in a hurry, so my advice, carry scissors to injure this evil foe.

baby evil mass destruction = bralette

A device that cradles a woman's boobs. This piece of clothing is used to hold the boobs up from their natural somewhat droopy position (depending on how big they are) in order to
1: Keep em from looking like the old woman on jackass number two: Very saggy and looks like a sock with a tennis ball in it (look in a national geographic mag, ugh, of course they are women who never wore one in their whole life).
2: To help eliminate severe bouncing action when the female walks, runs, or dances. They can be quite cumbersome without one while running. Because big ones can hit the face! But the male seems to be entertained by watching this action due to their enthrallment of big, round, firm, and tanned Breasts.
"WOW MAN! look at the size of her boobs, their gonna bust that bra right in half the way she moves!"

"WOW! I Went from an "A" cup bra to a "36 C" cup bra, all in the 7th grade!"
