TOP DEFINITION
Nut Riding
Defined as a tremendous or massive form of sucking up.
It is called nut riding because to the majority of men a nut ride is most pleasurable if delivered by a woman whom he is promiscuously copulating with because he likes her. The woman gains favor of the man because she has just greatly sucked up to him.
1. You think Greg will invite me to his party if I buy him some NBA tickets? Not to be nut riding or anything!
2. Did you see how she totally complimented him on that basket? She was totally nut riding.
