A verbal prank commonly used by in a
conversation, with the intent of annoying the listener. In this prank, there are two parties having a
conversation: person A (the pranked) and person B (the pranker). Person A makes a simple, innocent remark with no double meanings. Person B initiates the prank and replies, "I know what THAT means" (note the emphasis on the word "that").
The prank is that person A begins to feel insecure or
uncomfortable about what they have said, because the phrase, "I know what THAT means" gives the impression that person B misunderstood what was said (i.e. thinks it has a sexual meaning, or thinks they're lying about something). Person A is completely unaware that person B is just trying to annoy them.
After this, person B could proceed to only say, "I know what THAT means."
Dwight (person A): Hey man, I just
remembered, that new Eminem album is out today! Wanna go get it?
Jim (person B): I
know what THAT means...
Dwight: Um, what do you...think it means?
Jim: I
know what THAT means...
Dwight: **quizzical look on face** um, all I asked was, wanna get the new Eminem album...?
Jim: I know what THAT means...
Dwight: **getting kind of annoyed** do you wanna get the new Eminem album or not?
Jim: I know what THAT means...
Dwight: **more annoyed** what does it mean?! Eminem album or not?
Jim: I know what THAT me--
Dwight: **angry** WHAT? WHAT?!
Jim: I know wh--
