leaker 

The first person to leave his group of friends and go home during a fun late night out. This person will often try and slip out (i.e. leak out) unnoticed to avoid the embarrassment and shame of being the first to leave his buddies.

Man, it's only 10 o'clock and there goes Lamont. He is such a leaker.
