The practice of adding an unexpected fee onto a person's phone bill

"Call it 'cramming,' 'whamming' or 'super-slamming.' Call it what you will, but Lorraine Parker calls it a ripoff. Parker was shocked recently to find charges crammed deep into her phone bill for services she says she didn't authorize."

— Cam Simpson, "New phone scam: 'Cramming' your bill," Chicago Sun-Times, October 17, 1997

Of the three terms listed in the citation, above, the usage marketplace seems to have decreed "cramming" the winner over "whamming" and "super-slamming." That makes linguistic sense because this practice involves stuffing bogus charges onto otherwise-innocent phone bills, and "stuff" and "cram" are synonymous verbs.
