Knicker nappies are more fitting for Tena.
"I don't think I've ever called them anything, who ever actually talks about panty liners?"
My mobility has been poor for two years, i keep mine upstairs and on occasion when I've forgotten to bring one down, i might ask my DD to get me a liner (as opposed to a towel).
I've been asked by my DD, who wears tampons, if i have any liners.
Before we went out shopping, my then pregnant DD asked me to remind her to get liners, or she's asked me do i have any/pick some up.
I would think that anyone with DDs, or have house shared, have female relatives/close friends, would have these conversations.
The word panty doesn't grate on me because everyone wore panty girdles (60/70's) when i was growing up and they were advertised everywhere.
