To "Rofl" someone's "Copter" is meant to be sexual, and can take on any sexual connotation. Therefore, to rofl a copter could imply oral, sex, hands, or even weird creepy stuff like whacking off to Hannah Montana.
After all I did for Katie this Valentine's Day, she didn't even rofl my copter. What a bitchass.
