Being in a state of of extreme drunkenness, but unable to vocalise the much more
reasonable, 'Leathered as a handbag". i.e: the inability to identify the real phrase of the moment, instead reeling off many similar sounding phrases.
Any variation of the above is
acceptable.
i.e:
Leathered as a satchel
Satcheled as a handle bag,
Handlebaged as a leather.
Most variants are welcome.
