question:
I overheard my manager asking 'What are you up to?' What does that idiom mean? Is it an informal/negative way of asking??.
answer:
'What are you up to?' means 'What have you been doing lately?'. If you add an adverb to the end of the phrase, for instance, 'What are you up to tonight?' or 'What are you up to this summer?' it can be interpreted as 'What are you planning to do tonight?' or 'What are you planning to do this summer?'.


question:
Is there a word which has this definition: usage of vulgar or abusive words too often especially while chatting or talking to someone or while giving a speech. What do you call a person who uses abusive words too often without needing to.
answer:

Two adjectives come to my mind for a person who uses excessive foul language: 1) crass having or showing no understanding of what is proper or acceptable; rude and insensitive 2) vulgar (as you used in the title of your own question) not having or showing good manners, good taste, or politeness. Both of these suggestions are more reflective of the person's demeanor or temperament than the cursing itself, but I think they could be more colorful (pun intended) alternatives. I hope this is helpful to you!
