Your typical viral or spam email (or cyberprop) meant to either scare or amaze gullible or trustworthy people, who believe anything on the internet, and so get sent to you by your mom. The Mom emails that are making outlandish claims usually can be dis-proven by snopes.com. They most often contain large bolded text and have something to do with either politics or chemicals in house hold products. You will usually receive 3-4 of these emails at one time as moms don't check and send their emails as often.
AKA: an unsuspecting spammer... only it's your mom, and she doesn't send you enlargement adds.
NOTE: The content of these emails can also include not so funny jokes, or mildly amusing/amazing photos.
Mom emails include large bolded text like:
"PLEASE FORWARD TO ALL OF YOUR FRIENDS."
"DOES ANYONE OUT THERE KNOW HOW WE CAN STOP THIS....."
"I'm not breaking this one. If I get it a 1000 times, I'll forward it a 1000 times!"
