Examples:

Josh: Hey man. Do you think I should try and get her number. She is fiiiinnnnneee!

Mike: I see you Josh, I see you!

Mike : * Buys new Jordan's, and comes out wearing them*

Josh: Ohhhh, I see you Mike!

I see you
by Biotio Games May 6, 2020
When you "see" one of your friends flirting with the opposite sex, and sometimes the same sex.

Some of the times he/she may not even be flirting but in the situation you want to make shit awkward you may still "see" them.
(Person A walks up to person B and person C and sees them talking"

Person A: I see you!

Person B: Damn, he caught me...
Person C: Why does he see us?
