Here’s two interesting phrases in Brazilian Portuguese. One is to ‘flake’ on someone (which means to say you will show up for an event, then not show up), and that is ‘dar bolo para em alguém’ (to give cake to on someone). The other phrase is to be the ‘third wheel’ (which means to go out with two other people who are on a date), and that is ‘segurar a vela’ (to hold the candle).
