One who dislikes (hates) the band Paramore and continually makes derogatory comments about the band, even though Paramore rocks! They "hate" because they are insensitive about themselves and can't appreciate good music.
Parahater: Omg, I hate Paramore. Hayley Williams is so whiny.
Parawhore: She's not whiny! She can belt out major notes that you couldn't even hit with a bat.
Parahater: well... shut up.
