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!
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!!!
