Dildopotamus 

A dildo so large, one could find easier ways of inserting a hippo instead. Usually a gag gift, but you know if they make it somebody can sure the hell use it. As a derogatory remark, something (person, animal, thing, etc.) may be called a Dildopotamus in reference to the fact that besides looking like a dick, otherwise, they are useless.

I ordered some sex toys off the internet and they left this giant dildopotamus on my doorstep.

If you dont quit calling things a dildopotamus in front of the baby, shes going to wind up saying it.

Dipopotamus 

A person that will leave the premises without warning or at a moments notice.

We were all ready to leave for the club but our driver Jim pulled his usual move and dipped out without telling anyone and left us all without rides. That kid is such a dipopotamus!
