I don't ever say mate, I say "dude". 
I was with family members (who I dislike alot) and they are full on rednecks then were like to me "You are like a surfer" and bagged me out for not wearing a cow boy hat, jeans, a flanno etc Likeee 
And oh, they bagged me out once because someone cool occured and I said "Sweet" as in "hahaha yeah sweet", they thought I meant it in a girl way like "naw thats so sweet". What the actual fuuuk 

 These rednecks need a reality check.
