Navient
The semen that sometimes spurts into a man's navel when masturbating laying down.
I was jerking myself off while on hold with my student loan company and got navient all over my belly because I didn't have an extra hand.

(n) the lint that accumulates in one's naval when wearing a sweater.
I was on the phone with the student loans collections department and I pulled a piece of navient out of my belly button.
