pectenem

(Sp. model spelled same [pendéxo] < Vulgar Latin pectiniculum 'pubic hair,' diminutive of pectenem 'pubes')

   Hendrickson cites another source that glosses this term as "asshole." The DRAE defines it as a weak, cowardly man or a stupid, foolish man. It also refers figuratively to a person who lives a licentious lifestyle, a slattern. Santamaría concurs with the first two of these definitions and notes that in Mexico this term is derogatory and obscene, considered improper among well-mannered people.
