Attestations inShakespeare's time seem to suggest it was intended as mildly vulgar (comparezit) and metaphorical; see more atthis Open Literature article, which claimsWelsh as most probable origin:

• CompareWelshcibi,cibwst(“chilblain(s)”), although this itself may borrow from Middle English, and we may be dealing with some ancient unknown term. CompareEnglishgyve(“schackles”), a medieval word that might also take from Celtic.

There has been furthertheoretical conjecture as well:

• Assuming the origin English or Welsh derived from ispre-Celtic, somehave speculated a link to anOld European word from a British Vasconicsubstrate, in this case related toBasquegibiztin(“knot, bow”), compounded from a lost root*gibi,*kibi(“lump?”).

• kibed
• kiby
