look up any word, like bukkake:
 
1.
A dooduet is when two people are going the bathroom and decide to break out in song. This trend became popular in the late 1900s in both public and private bathrooms alike. It is not uncommon for someone to sneak into the bathroom while someone else is showering and start a dooduet by surprise. The more advanced someone becomes at a dooduet the more they can start to throw in a flatulent, a stomping of the feet, or a banging of the hands on a stall to add an instrumental beat.
“Hey man, what’re you up to this weekend”

“Going over to Taco City, that place always give me plenty of time to perfect my dooduet after scarfing down a burrito or two”

Example 2:
*Sitting in adjacent stalls in the movie theater

“Grease has to go down in history as a musical classic”

“Seriously man, that last song was awesome”

*In Unison
“We go together like rama lama lama ke ding a de dinga a dong remembered forever like shoo bop shoo wadda wadda yipitty boom de boom!”
