Shaymus
When you masterbate in front of your girlfriend while eating dinner.
I'm going to Shaymus all night long.
Shaymus
A man with great courage and a strong heart he leaves all other men jealous of his stunning looks and amazing talents. He's the most amazing guy you will ever meet and ladies who have a chance with him are very lucky. He's a keeper girls.
I think I'm falling for “shaymus”
Dirty Shaymus
A Dirty Shaymus is when you put your bong into someones asshole and light a bowl while the recipient sucks in with their ass. After the bowl is finished the recipient farts out the smoke and the person who lit the bowl sucks the air out of the asshole.
