When you're trying to remember the name of something to describe to someone and give up right in the middle.

#1: "It's that thing, you know that uh... what'cha'ma'fuckit..."
#2: "What???"
#1: "ADD kicked in, I dont care anymore..."

Whatcha-ma-fuckitt 

A component found in import-manufactured vehicles that is unidentifiable to even the most experienced of mechanics. All that is known is that the component is not an air-metering sensor (such as a MAP or MAF), it is not a purge valve, nor is a temp sensor, but it run back to the main wiring harness where the end connections are completely unidentifiable.

Often found next to the thingy-ma-jigger, but below the do-hickeys.

Now, we rewired the do-hickey, packed the bearings, replaced the hoosits, and flushed out the do-dad, but we still haven't figured out what to do with the whatcha-ma-fuckitt.
