A girl that isn't really a girl, she's a mixture, all the boys love mixtures. She's mostly bi-sexual because she likes the dick but she loves herself too much, which makes her love girls as well. A Leanne is a person who cares a lot, may not show it majority of the time, but she sure does. All the boys go wild just to get a piece of Leanne. Who doesn't love her. As much as she loves herself, she is quite insecure but doesn't wanna show it. She's a very social and intellectual person. She's the smartest girl you'd meet. Get you a Leanne. Very Independent and, and whatever you do, do not mess with a Leanne, she is quite fierce and can ruin your existence. But very sweet in general. Who wouldn't want to be friends with that amazing creature????!!!!!

Get the Leannemug. That girl is such a Leanne. She must have been locked in a castle for 50 years because she is so white and has not seen the sun. I bet those Leanne's never get skin cancer.

Chloe: 'Hey Leanne, I lost both of my legs in a horrific car accident!'
Leanne: 'Awww babe...that's cute!'
Leanne: 'Awww babe...that's cute!'

Get the Leannemug. Generally given to girls that are vertically challenged, they are generally of the cuntish variety and have little to no sense of humour.

Get the Leannemug. Leanne rules over Yugoslavia with an iron fist. She's a vengeful god who kills all in her path.
She even hires child labor to create false definitions about her on urban dictionary. Send help, water or bitches. Not. All. Three. We are dying, from lack of bitches. She keeps it -60 degrees in the child sweat shop because she says "if they're not sweating, it's not a sweat shop". My brittle dick has broken off.
