Like white girls on Halloween

Just like the best of us, white girls on Halloween will frequently wish to engage in some fun, casual sex, but rarely describe it as such. Often times the words "I don't have sex, I make LOVE" can be heard, uttered from a "sexy cop" on the spookiest night of the year. In this way, if someone is being unrealistically romantic about a sexual encounter, you might describe it as them "making love... like white girls on halloween"

Brad: Man this girl is SO hot, I just wanna make love to her
Chad: Yeah, okay bud... like white girls on Halloween
