Having spent the latter part of the afternoon and a portion of my evening worshipping at the porcelain altar I got to thinking about other descriptive terms for this sometimes unavoidable activity. FTR I have hypoglycemia and it was just one of those really bad days… you thought that I was out carousing perhaps?
Anyways… puke, spew, hurl, upchuck, blow chunks (your dog?), and worshipping at the porcelain altar come easily to mind…

I DONT know why, but when our first son was a baby, and he would spit up after every meal, one of us started calling it “bleck-ums”. Baby #2 is in my lap, and guess what??? Gotta go change my shirt again.
