When a girl tightens her pussy around your penis during sex; an embrace of cock similar to a hug.

a type of hug a girl gives to a guy.
in a song by murs, it's explained.
"Givin' you that look with pussy hugs all the time
Now let me take some time to explain the term
Pussy Hug means when a girl leans in
Arches her Back and her Pussy is the first thing to make contact
Then she slowly presses her tits against your chest
Then she finally wraps her arm around your neck
A blatant sign of disrespect
Its not hard to detect
Its something that your boy always neglects to check"
