When you get a food product knowing that you only want some of the contents and that the rest will be thrown out.

EX: Eating Marshmallows out of Lucky Charms and throwing the cereal away.
I got this new food for my dog and she totally has Lucky Charms syndrome, she keeps eating out the meaty bits and leaving the kibble part on the floor.

When you haven't done laundry in weeks, and the only underwear you left have to wear are back-of-the-drawer obnoxiously patterned/colored underwear that was likely purchased in your prepubescent years. When you sport such underwear, you at this time have what is known as a "lucky charm ass".
Her outfit is stunning, and it was pretty appalling when she bent over and I saw she had neon green unicorn underwear, a lucky charm ass if i'd ever seen one.

My one deal breaker is if the girl I'm hooking up with has a lucky charm ass. I want to feel like she's my age, not 12.

This is when a male and female are having intercourse and the male proceeds to pull out and ejaculate into the females mouth then pour cereal in and eat out of her mouth.

When you're pouring lucky charms and all of a sudden there is a certian part that has a bunch of LC marshmellows, Quite frequent if you buy bulk packages (From Sam's or ssomething) When hitting the LCJ usual emotions are Excitement and Joy. But be careful not to hit the jackpot to frequently or you will be left with the regular cereal, which sucks.
