Republican presidential nominee Donald Trump made a big speech in Detroit today, where he outlined his economic vision and maybe flubbed by saying the word "titties" instead of "cities" while addressing the Detroit Economic Club in Detroit, Michigan on Monday. 

Trump's speech was characteristically punctuated by protesters who showed up to interrupt his speech, while Trump supporters could be heard booing over chants, then applauding when protesters were removed. However, what's likely going to be most memorable about the speech were neither the vague ideas Trump offered to improve the U.S. economy, nor the protesters who showed up to shout him down, but rather the debate about whether or not Trump really did utter the word "titties" while trying to rile the crowd up.

The sentence that is now under intense scrutiny was uttered when Trump was discussing bringing wealth back to the country, "into cities [or titties?], like right here in Detroit."

While Trump could have said the word "cities" as was clearly intended in the speech, many on Twitter are convinced he goofed up and really did bring breasts into the realm of conservative economic policy, if accidentally.

As for his economic vision, which mostly consisted of criticizing his Democratic competition, Hillary Clinton, Trump said his campaign would roll out more details in the coming weeks, perhaps clearing some things up. But the mystery of whether or not Trump Freudian-slipped in front of the entire nation may remain a mystery forever.
