Oh brother...
As if "preggers" wasn't a bad enough (and believe me, it was BAD) lazy abbreviation for the word "pregnant", NOW, apparently "preggers" is outdated (oh joy), BUT the NEW abbreviation for pregnant is "preggo".
Really? "Preggers" SOUNDED like some kind of snack food or something, "Preggo" IS a food product: it's a spaghetti sauce brand!
What is so hard about saying the word "pregnant"? It's got no more, or no less syllables as "preg-gers" or "preg-go", and it sounds far less silly and ridiculous.
