agecuck

Someone who believes that women under some arbitrary age are a no-go for men above another arbitrary age (category that often includes himself, enhancing the cuckold aspect of it), but it's OK for men under a certain age to have sex with them.

Billie: Maybe try finding someone to date who ISN'T half your age or in college! This is disgusting and you should be ashamed!
Chad: She's of legal age, you fucking agecuck.
