referring to a woman who has large enough breasts that aren't proportionate to her body mass and makes her to appear that she has an ass on her chest when wearing a push up bra.
Ex.: a woman who is under 5' tall, weighs under 100 lbs. and has a size D cup breasts or a woman who is over 6' tall and under 170 lbs. and has a size G cup breasts.

FRIEND A: "Did you just take a stealthie of me?"
FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
