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.
