To perform a sexual act on another individual on public or group transport (such as a bus, train or plane). Sometimes but not always by a girl named Melissa.
"I fully saw this girl give this guy a Melsy on the train the other day"
or
"We were all so drunk on the way back from the wedding that Mel gave James a full 'Melsy' in front of everyone"
Melya is a genuine kind person who is utterly beautiful. She always has your back and is a wonderful friend. She feels like a warm hug in a warm blanket on a cold day. Melya's are, honestly, the best people ever. They are very curious and intelligent and love to ask questions. She is very shy and quiet but will beat anybody up to help you.
Guy 1: Yo, you see that girl over there? She is so perfect.
Guy 2: Yea man, that's Melya.
She is in all honesty is the most perfect girl that I have ever met. Without her I feel as if I am nothing but i waste of space. She has the cutest smile, the nicest eyes, and the kindest heart. There is nothing in the world I'd have other then her.
1 " Hey hows your relationship with Melyssa going?"
