The charitable consent to having sex with a less fortunate/ugly/awkward member of the opposite sex. Usually done at the request of the helpfukee's friends.
Tom walks into a shady bar with his ugly friend Bobby. After a few drinks, Tom walks up to the drunkest, sluttiest girl in the bar. He explains that his friend Bobby is extremely awkward with women and hasn't been laid in months. He then asks the girl if she could his friend Bobby a huge favor and agree to a helpfuk. A few minutes later, the girl takes Bobby home and has sex with him.
