bash

Bash means “to strike” something with great force. It’s been adopted as slang for hurling insults or verbal abuse at someone.

A bash is also an older slang term for “a wild party.”

Dating back to the 1600s, the simple verb bash is “to hit something with force.” It’s equivalent with the words strike and beat.

The use of bash for “a wild party” appears as slang by at least the 1940s.

Bash, for “to insult or verbally abuse,” emerged by the 1950s out of the original “striking” sense of the verb (i.e., hurling very harsh, even hateful criticism). One historic instance is queer-bashing, or slurring the LGBTQ community. Use of this bashing saw even more use due to cyberbullying, trolling, and internet comment culture.

What about the bash- in bashful, meaning “shy” or “timid”? The bash- in bashful actually comes from a shortened form of abash, “to make ashamed or embarrassed.” Abash is related to the word abase, and the verb bash likely imitates the sound of bashing or is influenced by words like bang, smash, and dash.

Bashing, for “violent blows,” is frequently used in expressions like bash one’s head against a wall or keyboard. Expect to see this when someone’s in the pique of anger or frustration.

Bash, for “insult,” is used in speech, writing, and social media. Expect to see this bash when someone (or the internet hive mind) is bashing a celebrity, product, or some other cultural phenomenon they dislike: He bashed Samsung’s new phone … or Twitter bashed Facebook’s corporate apology about hacking. A basher (e.g., anime-basher) is not unlike a troll or hater. Bashing, as in the general practice of insulting something, is common, too. For instance: Quit bashing on the new gamers in the forum.

Promote what you love, don't bash what you hate.
