שקצ

The exact meaning of 'seqex' is difficult to ascertain. It is typically translated as “abomination” and contextually it does appear to indicate an object of disgust and derision. It is often associated with the other members of the alehim aside from Ihoh.

Etymological evidence points to a possible literal interpretation of “kiss after” or perhaps “kiss the end”. The reader may make of that what they will.
