The action of spitting on your hand and either smacking or fingering a grandma
“Hey can I give you the wet grandma. ;)”
A Grandma Wet Lips is the ultimate thot. They can usually have 100-390,000 kids, and about 30 boyfriends at a time. They are perpetually 97 and never age. She ends up creating humongous families on accident, and occasionally can be seen working with the Mad Titan Thanos.
Oh god, here comes a Grandma Wet Lips and her 1,000 person family. I think we might die.
