When someone is saying
something that you have either
A) No clue what the fuck they are talking about, or
B) No interest in it whatsover.
It is basically saying "Shut the
fuck up" without offending the person talking. And hopefully, they will get the hint and shut the
fuck up.
Example A:
"So, if you just
take the
Rotation Muffler and place it into the X-axis, then you have a complete circuit."
".............I see what you're talking about."
Example B:
"So yeah, she lost the baby, dude. She's heartbroken about it."
"......I see what you're talking about."
"............You're an
asshole, dude."
