sheisty
adj.— «I’ve seen several bloggers use the term in different ways. In one case it seemed to mean “crappy,” which makes sense if it’s from the German “sheisse” (shit), but otter peeps don’t use it like that. “She got shiesty on me,” one blogger wrote, and in context it seemed to mean “weird” or possibly “suspicious.” Definitely not “shitty.”» —“Shiesty?” by Paul Light Ultrablog (Orange County, California) Jan. 18, 2005.
