Here are some of my favorites from their article:
Iktsuarpok, Inuit: To go outside to check if anyone is coming.
Jayus, Indonesian: A joke so poorly told and so unfunny that one cannot help but laugh.
Tartle, Scottish: The act of hesitating while introducing someone because you've forgotten his name.
Cafune, Brazillian Portuguese: The act of tenderly running one's fingers through someone's hair.
Tingo, Pascuense, Easter Island: The act of taking objects one desires from the house of a friend by gradually borrowing all of them.
Love it. These will come in handy on Twitter! Must save characters whenever possible!
