a northerner that have very thick accents and are often quite stuck-up. They typically think that they are walking geniuses and act like they know EVERYTHING which can be quite irritating. Yankees often think they have the right to travel to southern states and get the 'right' to try to correct southern 'rednecks' on how to speak, or what 'proper' grammar is. Yankees are often very judgemental of the southern 'rednecks' and put many of them down because they have accents or dont use proper grammar when really it's just the way that the southerners were raised, and assume that all southerners are 'uneducated, incestuous, and racist'. Yankees also have problems admitting when they are wrong and saying sorry, instead they choose to be smartasses about things.
(not all northerners/yankees are like this, but the vast majority of them are)
yankee: excuse me but please use proper grammar in MY presence (even though I'm the one that has traveled all the way to YOUR area I still have the right to correct you, cause like, I'm better than you) okay?
