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.

In a classroom setting- Making as little eye contact with the teacher or professor so you won't get called on.

In everyday life- Doing what you want all the way until you reach the level that you know you will get caught ridin dirty.
Classroom- I am staying under the radar not making eye contact in Contracts class, because I haven't done the reading for like a whole week!

Everyday life- Yesterday I made sure I was staying under the radar avoiding the boss's wrath at work by actually doing something besides sending e-mails and texting until my boss left for the day.
