A person who recklessly blows his nose and gets snot all over everything.
For example a tennis player who uses a finger to block one nostril then blows out the other nostril onto the court, not caring whether his opponent might slip on the snot after they change sides.
When you laugh so much you snort then you laugh more coz you snort making you snort again then the hands start clapping coz you snorted n laughed and laughed and snorted and you look like a seal clapping
