Slang for prison — the house that's built of iron bars instead of drywall. It's part of a long tradition of euphemistic and metaphorical names for incarceration, like 'the big house,' 'the joint,' or 'the can.' Iron house has a bleaker, more poetic ring to it — the permanence and hardness of iron standing in for everything oppressive about incarceration. You'll find it in older slang dictionaries and still occasionally in rap lyrics and street vernacular.
After the third offense, the judge sent him straight to the iron house with no discussion of probation.

Chicago-born slang for a brothel or bordello. 'Can house' was part of the city's early 20th-century underworld vocabulary, where shady establishments needed discreet labels. The term sits in the same murky drawer as 'house of ill repute' and 'disorderly house' — euphemisms that let people refer to the business without spelling it out. Rarely heard today outside of historical crime writing or Chicago blues lyrics, but it captures the blunt poetic genius of old-school American street talk.
