1. That guy. The silliest person in the room. Usually known to massive amounts of silly things.

2. Dance move also referred to as "the Big Sil". Only seen being done by those of an elite status at moments of inebriation.

A person calling you a 'big silly goose' is basically the gay way of saying "You're an asshole"
gay guy: Oh be quiet you big silly goose!

Strait guy: Shut the fuck up you gay ass bitch!

Used to stop a mexican form saying something that will make you look bad.

This will usually make you look better at the same time.
Mexican to group of John's friends-" Hey el pacho I saw at that taco bar with those gay strippers last night."

John-"Oh look at this big fat silly mexican! Soon he will have enough money to go cross the border back to his family!

Crowd of friends- "Ha you're the best John!"
