Where we used to live in Surrey and around in the home counties there were loads of places called bottom in an oo-er double entendre way.
The best was Pratts Bottom but there was Locks Bottom and then other funny non-bottom names - corkers like Nork (Norks=UK slang for breasts), Effingham, Uppingham, Upper Dicker (not to forget Lower Dicker), Jeffries Passage and Titty Hill in Surrey and W Sussex. As a result of this thought I looked to see if there's a website that lists the double entendre names in the UK and of course there was:
http://www.anglotopia.net/ultimate-list-of-funny-british-place-names/ I have to say that this made me laugh as there were a few that I have known all my life and never realised the funny connotations notably the little town in the Pennine hills which, phonetically spelled first - we pronounce as Penny-Stun but its spelt Penistone and seriously, I have never noticed the word Penis as a prefix, even when we passed the signs to it on the way home from a visit to Lancashire a few weeks ago!
Bottom is a common suffix in Lancashire surnames such as Ramsbottom, Winterbottom and Sidebottom. For just funny & quirky names Lancs (e.g. Eccles, Diggle, Oswaldtwistle) is a fund, as is Yorkshire (Dirt Pot, Humpswaite, Blubberhouses) and Cornwall (you get the drift!) particularly.
And in closing I just wanted to pay homage to the huge number of small towns in the US that have quirky or funny names too!
