Derived from the black & white movies of old when the ganster says to his 'moll' hey-ya toots... to which tutch has evolved as a term of indeerment a cute name for your beloved!
A very small person or amount; tiny. Originated from a famous music hall comedian from the late 1800s named "Little Tich," who was about four feet tall. Not to be confused with tetchy (irritable).
I went out with that boy again last night, and he sure was titchy, so I dumped him!
