Gr' in front, and usually in the plural.
Singular: - A left (or right) sailor's testicle that has been grossly inflated by a true '
blow' job in some stinking back-street
Asian or Arab port during shore leave.
Plural - (Gronions) The worst scenario. Both
balls about to explode through over-inflation, usually brought about by the aforesaid vicious fellatio, but with the added intervention of the house madam sticking a finger up the rectum at the same time.
Ship's Doctor:
'You seem to have a severe case of the Gronions'.
Sailor:
'Is there any cure?'
Ship's Doctor:
'No; but if you're willing, I suggest you donate one to
Arsenal and the other to Man.
U.'
