Traveller's smile 

The sign of someone who's fought a traveller. A scar caused by a pair of razorblades or Stanley knife blades concealed within a piece of cardboard. Since the skin tightens when cut, the two blades cause a nasty scar which sometimes never heals. It is often done down both sides of the face, so it forms a "smile" shape, hence the name.

Oh, my god. That guy's got a traveller's smile

plumber's smile 

a view of the top of the buttocks and gluteal cleft while a man's pants descend due to bending over(because it frequently happens to overweight plumbers, carpenters, etc.)

The plumber's smile that the road worker over there has is appalling.

Kiana's Smile 

You so fuckin' precious when you smile
Hit it from the back and drive you wild
Girl, I lose myself up in those eyes
I just had to let you know you're mine

Deku’s Smile 

The only thing that matters actually.

Random person: Is it just me or are there two sunshines now ?

Me: No, that’s just Deku’s Smile.

Joker's smile 

The smeared red lips resulting when one person performs cunnilingus on a woman during her time of the month. Resembles "the Joker" from Batman.

I was so drunk I didn't realize I ate her bloody snatch until the next day when I noticed I had a joker's smile in the mirror.

The Joker’s Smile

The joker’s smile is a sex move in which you have sex with a woman while she’s on her period. Right before you’re about to cum you pull out and nut on her face. You then take the palm of your hand and smear it to cover her entire face. You then take your dick with period blood on it and wipe it on her lips and up the cheek to resemble the joker’s makeup.

Yo! I just hooked up with a chick and did The Joker’s Smile on her! She was so surprised!
