what's-his/her/their-name

what's-his/her/their-name

Used to indicate a person whose name is not known or can't be remembered. Sometimes the hyphens and apostrophe are removed to form a single unbroken word. I heard old what's-his-name is back to teaching the course again next week. I ran into whatshername from next door down at the grocery store this morning.
