1) A female individual with a curvy, nice bottom. which others may find either beautiful or sexually attractive, or both.
2) Dat ass!
3) Urban
Dictionary's constant fetish. C'mon UD, it's obviously obvious, considering that whoever runs this place is always asking us to look up this definition.
Random note:
Number one rule: a person who is bootylicious requires a
hot, curved bottom, although emphasis on
hot. Not in any way can a fat person with a fat @ss be considered bootlicious.
