When a guy is having sex with a girl and she is bored so she watches tv as he is pumping away like a chump.
I watched part of an infomercial while he was chump pumping away. Sex is soooo soo on boring with him anymore

A person that manually bails a household sump after the electricity fails and they do not have a generator.
Dave and Sue spent all Saturday night working the chump pump because a tree took out their power lines.
