rusty bike chain

Eating out the ass of someone with braces than making them suck your dick and smile, showing shit stains on their teeth and braces

Guy: Suck my dirty dick!
Guy 2 sucks and smiles.
Guy: Dude, you got a rusty bike chain!

greasing the bike chain

Having a person who has braces blowing you than asking them to smile wide and busting the nut all over their braces.

Guy: "Smile wide, Brittany!"
Girl: "Why?"
Guy: "Cause I am going to be greasing the bike chain!"
Girl smiles.
SPLAT!!!
