semi young

For Females it's from like 25-30. After that you become a cougar. For guys it's 30-40. After that you become the old guy.

My girlfriend is turning 28 and worried that she's getting old and not gonna be young enough to score a guy. I tell her to relax, you are still semi young and can score a semi-young guy til your 30!
