dolmio grin

A dolmio grin is what happens when you go down on a girl when shes on her period and you get blood all around your mouth. It's called a dolmio grin because you get a similiar effect when you have lots of pasta topped with dolmio tomato paste.

Man I went down in this bitch and got the dolmio grin.

cheesy grin

Excited smile, often child-like from saying and holding the word 'cheese'. A cheesy grin is any teeth showing smile meant to project person's most pleasing facial expression in what is typically a happy time. The word cheesy-grin describes the teeth showing smile most often associated with a young excited child being told to hold a 'cheese' sound to hold a smile while getting their first portrait taken.

I am excited or told to smile, so I flash a 'cheesy grin'. The Cheesy Grin smiley emoticon (emotional icon or symbol) is a distinct teeth showing smile. Also known as 'cheesy smile'.
