means A person who's reluctant to spend money, even when they really should.

from The 'cheap' part is obvious enough, but 'skate' is the odd piece — it traces back to 'skate' as old slang for a worn-out, broken-down horse, used to describe a contemptible or worthless person. Bolt 'cheap' onto that sense of shabbiness and you get a 19th-century American slang coinage for someone whose stinginess makes them low-grade company.
