when people talk past tense about something that happen(s/ed) and repeat the word 'do' in a sentence and automatically you think of poop. if you just said do once the sentence would mean exactly the same thing and may even need fewer words but by adding a do to a do it makes the focus on poo which is a specific thing to do, do you think? so it's ok to giggle or laugh or offer a tissue when someone talks and says do do
i know you say you dont eat poop but you do do that -vs - i know you say you don't eat poop but you do
A do-do usually refers to an immature penis, but it can and is used to also, as a pejorative, to identify or describe the shrinking or always very small penis of an older or elderly white man.
