Oxymoron/Talk

I removed "jumbo shrimp" and the comments someone added because this comes down to a US vs British usage dispute. A scan of american dictionaries indicates that they deem "Shrimp" meaning "small" to be informal. A scan of British disctionaries indicates that "shrimp" meaning small is the primary usage, and the usage as a crustacean is a secondary one. Hence it IS an oxymoron to half the English speaking world, and is perfectly sensible to the other half. Rather than get into a protracted and longwinded explanation of trans-atlantic/pacific English issues, it was easier to simply remove it, as losing it doesn't hurt the article at all.
