Sparkle Pony 

A guy or girl you use for fun, but are not serious about. You keep them around because they make you feel good about yourself. It could be for one night, or for brief periods of time. Kind of like a "pool boy".

She is sad from the breakup, we need to find her a sparkle pony to cheer her up.
