Whilst a
person is engaged in conversation with another
person, one of the involved turns his/hers head during conversation, and pukes. Preferebly in the opposite direction of yours, but definitely not a must.
In rare cases, the person that vomits tries to finish the conversation after said vomiting. That is the sign that you are beholding a Grand Islandic
Dragon.
"Hey dude, anything cool happened at the cray fish
party last night?"
- "Nah, but I saw this dude pull off the islandic
dragon in front of another dude. A bloody miracle he didn't get any on the dude's shoes, dude was spraying like a
motherfucker."
