I'm fluent in both Spanish and English (obv). When speaking English, I'm conflicted on whether I should pronounce Spanish loan words in a shitty English accent like everyone else, or in a proper Spanish accent. So instead I pronounce them as horribly as I can.
Jalapeño is "yah-la-PEEN-oh". Fajita is "fa-JAI-tah". Quesadilla gets "QUAY-sah-dilah"
(As a joke of course)
