Back-seat Browsing 

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.

Person1: Does Percy know?

Person 2: Hell no man, otherwise he would be so pissed.

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.

back seat lifing 

Like 'back seat driving', back seat lifing means a more knowledgable person will want to help the stuggling person with all decisions, as they clearly have no idea of what they are doing. A back seat lifer has been there and done that many times before and just wants to pass on his immense knowledge of everything.

Man walks in holding a beer, another man back seat lifing says "don't hold it like that, it should be held like this"

Man sharpening a pencil, another man back seat lifing says "don't sharpen it like that, it should be sharpened like this"

Man standing minding his own business man back seat lifing says "don't stand there like that, you should be standing like this"
