a person/friend that will provide you with sexual favors at the drop of a hat.
At a bar...trying to pick up women. You notice that "pocket lint" is there. You try to pick up other women in the meantime, and if you are unsuccessful, old reliable "pocket lint" is there ready to go home with you.

Exs that never seem to go to far away and always seem to be stuck in your pocket no matter if you think you remove them or not there they are
My pocket lint called me on the phone last night telling me how much they love and miss me they can't seem to understand I have moved one
