Here's a fun piece of etymolgy that I hope won't get edited out. Remember that in rhyming slang the rhyming part can get left out so apples and pears = stairs can become apples.
How *** became aris:
Rhyming slang for *** = bottle and glass. Shortened to bottle. Rhyming slang for bottle = Aristotle. Shortened to aris. I wonder what the next step will be?
