slang One who is apt to drink alcohol often and excessively. "Hooch" is a slang name for liquor, especially that which has been made or sold illegally. Geez, if we go to the bar a third time this week, we're gonna look like a couple of hooch heads! I used to be a real hooch head and spent all of my time in bars, but that was before I went to rehab.
