sneaky fat

1.) the kind of fat where a persons body appears to be skinny, but they have fat that isnt visible until the body is naked. 2.) Every fat person's profile picture and you have to go through all their pictures because they take them all themselves from a top angle to hide how fat they really are, but somehow one manages to slip through that shows a whole body shot. 3.) similar to the "wonderbra effect", or stuffing of your pants.

1.) That bitch was sneaky fat man, had to lift up her roll just to dick it.
2.) That girl looked cute but she was sneaky fat, I didn't notice until her last picture where i saw her body.
