I did too until I learned (two minutes ago) that Beaner is a derogatory slur originally from the United States to refer to individuals of Hispanic or Latino descent, particularly those that are Mexicans from Mexico or of Mexican American descent. source: Wikipedia
That sucks, I don‘t think we should let slurs ruin an otherwise perfectly fine word like bean, I love beans, but maybe it‘s not the best choice then. Guess we could do some poll to see how other names fare though.
