The single greatest specimen to ever walk gods green earth. If you've ever been near Li'l Sebastian he no doubt stole your very soul. Unless your name is Ben. Also known to be one of the only things to make a Ron Swanson giggle like a little school girl.
A Li'l Twat Munchiken Arsehole can be defined as a male most likely around the ages of 40 who was unlucky enough to have the blessings of god and thus lacks the gift of puberty. Basicallyanother word for "small pp boy" but just add a bit of McGregor twist to it.
I pity Yohan for being a Li'l Twat Munchiken Arsehole, its fine if he can't cum, adoption is an option.
A pop culture phenomenon everybody else loves but you just do not "get it." This is not necessarily a case of disliking the phenomenon, but more a case of being completely dumbfounded as to why it is popular in the first place.
Origin- Season 3, Episode 7 of NBC's 'Park and 'Recreation,' Ben (Adam Scott) does not understand the town's obsession with a mini-horse named Li’l Sebastian.
While his coworkers played Angry Birds during their coffee breaks, Ted viewed the game and their obsession as a real Li’l Sebastian.
