Your "things" name

I have many names: Lucifer, Satan, George Bush...

Oh? My cock? My cock has answered to the name(s):

Max
Barbie
Mini Me
George

In non-bedroom usage, I call it a dick. People say dick sounds small and cock sounds more "manly" but cock is also American and I try to avoid Americanisms since I am not American.
 
I don't have any name for it, but

every once in a while I'll use the word "dingus" instead of "whatchmacallit"

people around me usually take that to mean I'm referring to that thing
