fly under the radar

To act sneaky and secretly without other peoples know about it. To act furtively.

Guy 1 - Have you seen those news about the mobsters of L.A.?
Guy 2 - Oh yes, I have. They were finally discovered, working undergrounds.
Guy 1 - Haha, they were flying under the radar of our city police, but sooner or later they would be found.
Guy 2 - To fly under the radar is no easy deal, here in L.A. ... One hour or other they catch you.

Fly Under the Radar

When your about to have sex with a woman doggy style and the woman has a fat ass. To reach the pussy you must lift up her butt cheeks and fly under the radar to have sex. This can also happen when a woman have a f.u.p.a and you have to lift the f.u.p.a up to reach her pussy.

Greg: Dude your girlfriend has a fat ass! What is that like when you bang her from behind?
Jack: Well I have to Fly Under the Radar to reach her pussy.
Greg: Oh My God.
