When you and someone else, preferably a fried agree on something or say something at the same time and then perform this sequence in awesomeness. Or when something great happens.

1.To "pound it" you must punch each others fist together.
2.To "lock it", you twist your fists in opposite directions signifying the "locking".
3. Then to "chain it", you slide your wrists towards each other.
4. Then EXPLOSION is done by moving your hands away from each other with open hands quickly and saying "explosion"
5. Finally, right after the explosion, you wiggle the fingers on both of your hands pointed at the other person like you are doing a magical spell on them.
