In English, “biro” is the generic name for what is known elsewhere as a “ball-point” or “ball pen”. There may of course still be a “Biro” company somewhere, separate to that.
[Edit] I mean English as in “language spoken in England” - I’m sure some of the other “Englishes” use a different word.

Don’t move your butt,
