LRB 

LRB is an abbreviation for “Little Red Bird” recognised in some cultures as an omnipotent being.

The LRB can, as legend goes, teleport, fly, have super speed and the ability to transcend the reality we know.

The LRB inspired the design and character story for Rovio’s “Red”, the main protagonist of the Angry Birds series.

LRB 

Little Rich Bitch - A young woman who is growing up with Daddy's credit card, has her "own" car, living in a big house and thinking she is better than those who aren't lucky enough to be privileged in that way. She expects somewhat expensive dates, rides in cars that aren't clunkers and gifts. Usually not fat, yet. These are high-maintenance, good-looking broads who usually aren't worth it.

That LRB walking up here expecting me to pay for dinner.
