I like to think of it as taking a person's (negative) forward momentum and using it to grab them up and whirl them around rockabilly style, all the while putting them completely off balance.  I had that poor devil dancing his feet off for several weeks, hehehe.

OT: And to your other question, nah, I'm not killing  you with kindness, just serving you up your just desserts.  It's a karma thing.... pass it on.  :-D
