Is there a name for this drink?

Lately I've become fond of reverse martinis with a 2:1 ratio of dry vermouth to gin. More recently, I decided to try squeezing lemon juice (usually one or one-half of a lemon's worth) into it. It's pretty good!

I searched online to see if anyone had done this before, or if this drink had a name, but all the results for "lemon juice martini" are for the lemon drop martini, which is very much not what I'm looking for (I'm not a vodka drinker). Have I invented a new drink by accident?
