ankle shakes
The most honorable way to consecrate a promise. Breaking an ankle shake is like breaking a pinky promise but 100 times worse. If you ankle shake on something you mean it and your promise can't be broken by any means

Frank: Yeah she did bro, there's no breaking ankle shakes!!
Frank: Yeah she did bro, there's no breaking ankle shakes!!
