Interesting change in direction and question!

I'd say it's when you don't play on the beat... (duh.. )

Think of a normal (e.g. techno) beat ( ||: 1-and-2-and-3-and-4-and-:|| ) when the bass drum play on the beats and you play on every "and".

This is a weak explanation on how I understand it, but I've never heard any definition of it so please correct me if I'm wrong on this one...

 

Yeah you could also count like this.

1 e and uh 2 e and uh 3 e and uh 4 e and uh BOOM!!!!

play around with the e and uh parts and slam the 1 hard occasionally that's pretty funky. But a lot of it is getting the feel down. Practice this with a metronome.
