Sebastian

(Verb) stomp your feet loudly, shit your pants and breath heavily in someone's face.

(Noun) an autistic gay italian boy that loves to harass women and check out their boyfriends. He is about 400 pounds and walks like he's gotta shit 24-7. He also loves to say hello by staring at you and calling you hot. He wears a pink hoodie and is really easy to spot in public.

"Oh shit, It's Sebastian. We gotta go, Marline. Hold down the fort for us and hold on for your dear life, Iceberg right ahead!"

"AAAAHHHHHHHHH!!! We're too late!"
