hork

The story

Onomatopoeia or imitative. For “cough up” sense, compare hawk/hock (16th century), which are almost homophonous in non-rhotic accents. For “throw” sense, compare huck. The “foul up” sense is presumably influenced by bork (late 1990s), from broken. The “steal” sense may be related to hook, which has the same slang meaning.
