Someone with a tiny penis that hasn't been laid in approximately 2 years. Merty's are bitches and still live with their parents. They suffer from premature ejaculation and go soft the second they stick it in (the main reason its been 2 years). Mertys have no friends, just acquaintances that feel bad for him so they allow him to hang out for a while.
