?? Name for people who had their WLS surgery the same day ???

There should be a semi-official name for people who had their surgery the same day, and therefore went through this amazing life-changing experience 'together', even if miles apart... Does anyone know of anything that people have been using? Thoughts that come to mind - 'surgery buddy/pal' 'surgery brother/sister' trying to work 'twin' in there somehow, but since there were so many of us listed (and I'm sure even more not listed) from 2/27, it would be much more than twins or triplets or even octuplets lol Just one of those crazy thoughts that run through your head.. ...Nick
