Top definition
A singing style characterized by senseless, tasteless and gratuitous vocal embellishments including, but not limited to, unending grupettos, raspy whispering, vocalized telephone-trills, and whistle-range experimentation.

As the root word implies, this style of singing is best exemplified by pop superstar Christina Aguilera.

Listeners exposed to Aguileraitis can expect to experience ringing ears, headache, and even, occasionally, projectile vomiting.
Sam: Did you see Maya Rudolph in that National Anthem skit on SNL the other night?

Dave: Yes, wasn't she great?!?

Sam: Yeah, her character totally had Aguileraitis!
