Plain girl attractive.
Basically a girl who isn't particularly slim or chubby, has average sized
tits, average curves, average length hair, is neither
popular nor unpopular and is generally average at everything. Isn't particularly attractive, but still isn't unattractive.
Average and
popular boys won't blink an eyelid at her, but the not-so-popular boys crush on her because she's considered not too far out of their league. Often gets a lot of unwanted male attention.
Popular girl 1: How the hell did she get half of the nerds to drool over her? She's not
even that hot!
Popular girl 2: She's just PGA, you know,
plain girl
attractive.
