noun-the amount of money a guy spends to get and keep a girlfriend. It includes spending money on things such as dates, gifts, and even upping your wardrobe or standard of living to keep her happy. When a guy is single, he can use the money he would normally spend on his girlfriend to justify buying himself expensive gifts or anything else he wants that's normally out of his budget. Since his girlfriend would normally receive the benefit from his money, he doesn't need to feel bad about splurging on himself
"Yo, that's a sick watch Son! How did you afford that?"

"Easy, I took it out of my girlfriend fund since I broke up with mine last week. 'Spend it on me!' You feel me?"
