A sycophant or ass (arse) kisser who does not know when to let go. Gives people unwanted attention or compliments, especially when least convenient.
That leg humper of a neighbor sent me a thank you card with flowers for lending her some sugar.

"You're so nice, charming, decent, generous, gracious, captivating..."
"Stop humping my leg! Just did what anyone would have done."

They see a decent picture of a girl online and go totally nuts and bothers the girl thinking they will get laid someday.

1) A person whose constant quest for any part of the spotlight or access to situations they deem special/important makes them take on the persona of a non-neutered dog.

2) The persistent act of attempting to experience achievement by the mere act of forcing one's body close to and/or upon an achiever.

3) The only act a truly lazy individual is able to exert in their quest to achieve dreams that were never theirs...but seem really cool once they hear about it.
Jill never had time to help Bobby make a success of his blog. But now that sponsorships are up and Oprah's calling, she won't go away. She's such a LEG HUMPER.

If you win the lottery, every leg humper from here to kingdom come will show up as a brand new distant cousin.

Leg Humpers are the "close talkers" in the world of interpersonal relationships. They neither see nor care about appropriate boundaries.

Someone who is always hugging somebody or sitting on their lap, especially if they are petty, anal-retentive, and a control freak. See Ellen; usually a spoiled brat.
This girl in my French class is a leg-humper.
