Crab Eyes 

Usually used when referring to a person that either slightly or largely resembles a crab. You can spot a crab eye straight away by measuring the distance between the eyes, usually atleast 5cm apart.

Although a crab eye could seem quite cute or friendly at first, do not be fooled, as their black beady eyes hold many sinister powers.

Look a crab eye in the crab eyes and it could be the last thing you ever do.

Tom: "OMG check out that crab eye."
Lisa: "EW that's gotta be atleast 10cm on that one!"
Tom: "It's actually quite cute."
Lisa: "Don't look it in the crab eyes!!"
Tom dies.

It's so cold out, Wendy got the crab eyes. She could cut glass with those things.

Crab eyes 

When someone sends a picture of their lounge view and protruding big toes are exposed. Typically this is an ocean-view with big toes photo-bombing the picture.

Common reaction to such a photo is to write "CRAB EYES!" In the comments

What a lovely view, save for the crab eyes in the foreground.
