Yippy Skippy!

If I was feeling in a gerundish sort of mood, I would say Yipping Skipping!

If I was feeling in a gerundish sort of mood combined with a desire to uses "L", I would say Yippling Skippling!! 

Now I should say that yippy skippy is something I say when I am in a good mood!

I am in a good mood because my wife got her multiple-entry Canadian Visa good till her passport expires sometime in 2021!!
