Additive rhythm - ever heard of it?

A few weeks back, I started working on a new piece of music on guitar, and kept tripping up on the timing and didn't know why... so I figured I accidentally wrote a piece of music in a different time signature than 4/4.
Counting it out, i started to think it was 3/4, as there was an obvious 1-2-3, 1-2-3 to it. But something still seemed odd, so I sat down at the sequencer with a few drum samples and setup a 3/4 time sig and gave it a go, and it didn't work.
Thinking back to some of the few music books i've looked at, I recalled how "Here comes the Sun" has multiple time sig changes in a single measure (4/4, 2/4, 3/8 then next measure 5/8, 4/4, 2/4, 3/8 - and no i can't play that!). So in my sequencer, after 2 sets of 3 beats, I added a change to 4/4 for 2 beats, picked up the guitar... and that was it!
The count is: 1, 2, 3 - 1, 2, 3 - 1, 2
So i started wondering if this had a name or a way means to notate it... and there is: 
3+3+2/8

=====================
In music, an additive rhythm is a rhythm in which larger periods of time are constructed from sequences of smaller rhythmic units added to the end of the previous unit. This is contrasted with divisive rhythms, in which a larger period of time is divided into smaller rhythmic units.
The term additive rhythm is also often used to refer to what are also incorrectly called asymmetric rhythms and even irregular rhythms - that is, metres which have a regular pattern of beats of uneven length. For example, the time signature 4/4 indicates each bar is eight quavers long, and has four beats, each a crotchet (that is, two quavers) long. The asymmetric time signature 3+3+2/8, on the other hand, while also having eight quavers in a bar, divides them into three beats, the first three quavers long, the second three quavers long, and the last just two quavers long.

I tend to "quaver" in my boots when it comes to odd time signatures
not an Obliminal thought in his head
