Once-ler; The epitomy of Ryan Ross. He is in The lorax movie, and has many smutty fanfics written about him.

A character that is in the lorax. He has nice legs and is fucking sexy, he also has a fandom that is gonna revive next year.

A faggot ass tree choppin bitch and there moms a thot

Someone who simps for the once-ler. Mainly tumblr user or 13/14 year old girls who have seen the Lorax to many times. Once-ler simp makes you breedable and submissive, you may also be a simp for Daniel from camp camp. These type of people probably read wattpadd fics self inserts like one direction.
