1869

‘South-Western Sl.’ in Overland Monthly (CA) Aug. 131: When a Texan goes forth on a sparking errand, he does not go to pay his devoirs to his Amaryllis, his Lalage, his Dulcinea, or other such antiquated object of affection, but (employing a word worthy of a place in the pasilaly of mankind) his ‘jimpsecute.’ She, on the other hand, is said to receive attention from her ‘juicy-spicy’.
