I really hate it when people can't differentiate between two words that LOOK similar, but mean horribly different things.

For example, someone once sent me many many emails, before finishing off with a "Sorry for all the spasm!"

Apparently, someone thinks that all those emails that usually go into your Junk folder are called "spasms". So I wonder what those jerky actions that come about as a result of fits or something are called. I suppose she would refer to them as "spam". Like, "Damn, could you please stop thrashing around wildly over there? You're really spamming me!"

And of course, you'd get, in your Inbox:

"What? I'll get a million dollars if I give you my account deta-ARGHHHH SDFDKHGJHFDJ HAHGJ HASDJFHAJ SDHFJ ADFHKAJSDFKJASKGJKSDFJKSJDHS??!!?!?!?!"

...spasm mail.

If you didn't get that, shame on you. It was such an obvious joke.
