The term "buzzing" has multiple meanings depending on its context.
1) In a general sense, it can refer to any continuous low-pitched humming or whirring sound made by an insect's wings, machinery, or other sources. For example, "I could hear the buzzing of bees outside."
2) It can also mean creating excitement or interest through word of mouth or social media. For instance, "The new restaurant is really buzzing right now."
3) In a more specific sense, it refers to the act of using electronic devices such as smartphones, tablets, and laptops for communication via text messages, emails, or instant messaging services. An example sentence would be: "I'll send you a buzz when I arrive."
4) Finally, in some regions, particularly in North America, the term can also refer to an alcoholic drink, usually beer, that is served in large quantities at a low price. For instance, "Let's grab a few buckets of beers before we hit the club."
