IBM:
Or: I.B.M.:1. Jocular acronym (often symbolized by holding up the little finger) for Itty Bitty Meat, a small penis , punnig the computer giant (International Business Machines) using the same initials. US origin and usage.
2. Roger Mellie in Roger's Profanisaurus (1998) gives another interpretation: ' Inches Below Muff. The units in which a skirt is measured .' As is often the case-with Roger it's hard to tell if this is an acurate description of usage in the UK or the product of his fertile imagination . I've never heard this in Canada or the US.
