Is slug a swear word

Answer 1

No, it is not a swear word, but it can be a slang word. That means you would not use it in a formal or business conversation. The most common slang meaning of this word is "to hit someone very hard." If he doesn't stop bothering me, I am going to have to slug him.

You will also hear "slug" in Baseball, where a player who hits a lot of home-runs is often called a "slugger." A slug can also refer to a metal disc, shaped like a coin, which can be used in a slot machine. But none of these uses is considered a swear word.
