French. self-esteem; self-respect.
The French compound noun amour-propre, literally “self-love, self-regard,” is associated especially with the philosophy of Jean-Jacques Rousseau (1712-78), but the phrase is found earlier in the works of Blaise Pascal (1623-62) and François de La Rochefoucauld (1613-80). For Rousseau amour-propre is self-love or self-esteem dependent upon the good opinion of others, as opposed to amour de soi, which also means “self-love” but is directed solely toward one’s own well-being and is not dependent upon the good opinion of others. The English lexicographer Henry W. Fowler (1858-1933), in his A Dictionary of Modern English Usage (1926), acidly comments about amour-propre, “Vanity usually gives the meaning as well, &, if as well, then better.” Amour-propre entered English in the 18th century.

Slang. a helicopter.
Eggbeater in the sense “small, hand-operated rotary appliance used for beating eggs” has existed in English since the 1830s. Eggbeater in the sense “helicopter” was originally an American slang term used by pilots of fixed-wing aircraft for the newfangled helicopter, the rotary action of whose blades looked to them somewhat like the rotary action of the familiar kitchen appliance. Eggbeater in the aircraft sense dates from the 1930s.
