A scientificinstrument used to measeure dildons. Dildon is a derived term, like Newton, to represent dildoes per square foot.
Mr T: Whoa, I'm picking up 34 Dildons on my TI Super Dildometer!
Chuck Norris: Someone has alot of dildoes around here!!!
Your Mom: Oh, that's just me. ;-)
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.
