One Dump Chump 

A man that can only ejaculate once and cannot recover for another round. This is not to be confused with a one minute man, as it has very little to do with stamina and the longevity of the session.

My husband takes forever to bust a nut but once he does he's a One Dump Chump.

Credit dump chump 

Somebody who uses a credit card as a debit card would normally be used in order to accrue cash-back benefits. However, they're chumps...

That guy has so much debt he must be a credit dump chump.

Chump Dump 

When, the morning after she DIDN'T bang a guy otherwise ends up in her bed,a girl finds it in the kindness of her heart to throw on a sports bra and some flip flops and drive the poor man home.

Girl 1: Wow, why are you up so early on a Saturday?

Girl 2: I had to Chump Dump this dude before his hangover lifted enough that he tried for morning sex.

Dumphump 

A dumphump occurs when you bang a chick while you're taking a dump. Shitting, wiping your ass, and then banging while sitting on the toilet is not considered a dumphump. You have to be in the process of shitting while banging for it to be considered a true dumphump. If you can time it out so that you blow a load as a huge turd is coming out, that feels great. A dumphump does not have to be performed on/over the toilet. You could fuck your girlfriend from behind and shit on your bedroom floor while doing it, and that would be considered a dumphump also. Basically, if you're shitting anywhere, while banging a chick, that is a dumphump. It's a little known fact that 32% of women have more intense orgasms when they are breathing in the smell of shit. If you haven't tried the dumphump yet, try it soon.

Todd: "Did you nail Rebecca yet you dirtbag?"
Ron: "I did more than bang her little guy, I dumphumped her at that frat party."
