Sinclair

A weirdo pedo looking skinny guy. Likes sports, yet still looks as a child is about to jump from under his overcoat.

Check out that Sinclair over there, is that a kid he’s with?

Sinclair fit

A ridiculous outburst of mentally retarded anger for seemingly no reason, pronounced- sin-kler fit

Man I was at my buddy Connor’s place last night and he had a massive Sinclair fit

Sinclair

A boy with the most amazing sense of humour, he will make you smile on your worst days. Has sandy/dirty blonde hair and sparkling green eyes that make you warm inside. He may be weird sometimes but in a good way. He's very athletic and plays basketball and soccer. When he smiles at you, you'll get butterflies in your stomach. Sinclair is very popular with the girls and has many friends. Very smart and gets good grades and is one of the sweetest boys you'll ever encounter.

Love the Sinclair in your life <3
