Megs are nice as hell, funny as hell, likeable as hell, cute as hell--basically, she's fucking hell. She's a heartbreaker without realizing it. Meg might be short for Megan or Megumi. She is the vision of a perfect girl. If you fall for a Meg and she falls for you, you have the title of the luckiest dude in the world. If she doesn't feel for you, you're in deep shit. Symptoms include: depression, insomnia, increased stuttering, increased staring at her, and increased praying to God.
Dear God,

Have mercy, I am dying. End these feelings for Meg quickly, I beg of you.
