An annoying twat who sits behind you just watching you browse the internet or my documents. Anything. Anything they can get their watchful eyes onto. This could be you brother, your best friend or a stranger at the libary.

Person 1: What's Tim doing.

Person 2: oh he's just Back-seat Browsing on Percy over there.

Back-Seat Baby 

A baby conceived from having sex in a car, usually, but not limited to, the backseat.

Because Ricky and Charlotte have only had sex once, in the back-seat of his car, and she is now pregnant, her child would be considered a Back-Seat Baby.

In alpine skiing, being in a position where one's center-of-mass is shifted toward the tails of the skis instead of toward the tips. Results in reduced control, adaptability to changing terrain, and ability to make a full turn.

I hit that rut hard and got thrown into the back seat.
