for cereal 

A very stupid way of saying "for real".

People who find this annoying phrase funny, or worse, actually use it in conversation, whether real or online, are complete and total retards.

It should also be noted that there is a positive correlation between how much you use this phrase and just how big of a retard you really are.

Person 1: "Hey, my grandma is a leprechaun!"
Person 2: "For cereal?"
Person 1: "No, yours is you retard."

For cereal?! 

A COOLER way of saying "FORREALZ?" Other forms of the expression is "Cereally?" and "OMGFORCEREAL?"
When you say it, you usually jump up and down and make flailing arm movements.

"I JUST WON THE LOTTERY!"
"OMGFORCEREAL?!?!"
"wow. you just ruined my win by saying that."

(teenage girl)"SO I WAS LIKE "FOR CEREAL?!" AND HE WAS LIKE "YEEEE-YUHHH!!" THEN I WAS LIKE "OHMAHGAH!!!"
