Umpteen

My mother liked the term umpteen. She would say "If  I've told you once I've told you umpteen times".

The word is an early 20th century one they say (probably army slang) and, of course, means an indefinite number. The dash in Morse Code can be referred to as the umpty and that may be the source of this British informal term.
