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."
