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."
