white feather (n.)
as a symbol of cowardice, 1785, said to be from the time when cock-fighting was respectable, and when the strain of game-cock in vogue had no white feathers, so that "having a white feather, is proof he is not of the true game breed" [Grose].

pina colada (n.)

"long drink made with pineapple juice, rum, and coconut," 1923, from Spanish piña colada, literally "strained pineapple." The first word was originally "pine-cone" (and formerly pinna), from Latin pinea (see pineapple). Second word ultimately is from Latin colare "to strain" (see colander). Ayto ("Diner's Dictionary") writes that the drink probably originated in Puerto Rico and "enjoyed a certain vogue in the mid to late 1970s," as evidenced by a certain song.
