The Lithuanian Love Puddle is where you have sex with a woman and she leaves a really big wet patch, like bigger than normal. It's called 'Lithuanian' because women from that region love sex, any way, anytime, in any hole and usually leave a massive wet patch behind!
Sammy, I took that girl I met back to my place last night and I ended up giving her the love thrust whilst she was sitting on my kitchen bench. Anyway the next morning I got up and she had left a "Lithuanian Love Puddle" all over the kitchen floor. Lucky I cleaned it up before the dog did hey!
