Used primarily in southern
Maryland, trueman, when used as a noun, is
slang for "gypsy." It is also used as an exclamation when a
toad is found near one's mailbox.
Example 1,
slang for gypsy: "I went to see a fortune-telling trueman to find out if
Kristin is in love with me. I think the trueman put a hex on me instead. I should have tipped her."
Example 2, as an exclamation: "Trueman!
Ugh, toads are so gross."
