I think the comments are the most revealing. It's not that it's in a 5/8 with some odd microtiming, but that it's some kind of additive rhythm: https://en.wikipedia.org/wiki/Additive_rhythm_and_divisive_r...

This reminds me of the famous Dave Brubeck Quartet song Blue Rondo a la Turk, which has a 2+2+3 rhythm, and I always remember the rhythm by remembering, "Taco taco taco burrito."
