This is funny. I've never thought about it before, but I guess we have adopted a few words into our family vernacular. It'll be interesting to see what sticks around long term.
The remote for the computer (which we use as our television and also for playing music) = Little Tiny Remote, which then became LTR. I'm certain this one will be around as long as we own the LTR.
Blow Nose = the soft flannel wipes I keep in the tissue box.
Those are the only two I can think of that we still use.
