The Highlighter is a sex act in which the male, while on top, pulls out, and when he finishes leaves some of his seed in the female's hair, thereby giving her highlights.

This act is best performed when the male is drunk enough to just sit there and laugh while the female freaks out.

Additional bonus if after The Highlighter is performed, the female returns for a second round of sex.
