A backpack mounted rocket launcher originally used by Reinforcements of the Cheat Commandos. Handy for taking out those pesky enemy radar dishes.
"Justice Rocket Backpack Rocket Rocket Fire!!", Reinforcements said while taking out the enemy radar dish.

Refers to a huge affectionate squeezy-clasp whereby you wrap both your arms and legs around da person, so dat you are suspended off da ground from da other person at four attachment-points, like a strap-on bookbag.
Backpack hugs are awesome; just make sure dat da person whom you're giving one to is large and physically strong enough to safely support your entire body-weight like dat.
