It's all Internetese. The one that bugs me (well, one of the many) is "Walla." Not the town in Washington state. As in:
"I wanted to surprise my nephew for his birthday so I hid the new tricycle under a sheet. When he walked in, I whipped the sheet off and ... WALLA ... there was the tricycle."
As the Irish are reputed to have said on occasion, "Saints prezairv us."
