[Q]: 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 excellent choices exist. The first can be used as either an adjective or noun, in slightly different forms: foulmouth, adj. and n. B. n. A foul-mouthed person. ["foulmouth, adj. and n.". OED Online. June 2016. Oxford University Press. (accessed August 21, 2016).] The adjective 'foulmouth' is obsolete in that form. Instead, the current version is 'foulmouthed': foul-mouthed, adj. Of persons and their utterances: Using obscene, profane, or scurrilous language. ["foul-mouthed, adj.". OED Online. June 2016. Oxford University Press. (accessed August 21, 2016).] The second choice is not so commonly used, and is only found as a noun. However, there's no mistaking its meaning: muck-spout n. regional and slang a person who uses obscene or foul language. ["muck, n.1". OED Online. June 2016. Oxford University Press. (accessed August 21, 2016).].

[Q]: Question: I understand the capitalization rule for nouns, proper nouns require a capital letter. Also, I should begin a new sentence with a capital letter. When & why "mom/dad" requires a capital letter ? (Reference- ELL- I am at Vapi where mom is hospitalised) mom: (n) informal term for a mother/North American term for mum. 
Answer: We should capitalize these words if they are being used as the name of the person. You can capitalize these when referring to your own relatives: Hello, Mother. When you use mom/dad in general meaning father/mother, it's a common noun. So do not capitalize them when they follow possessive pronouns such as her, his, my, our, your. (my mother ~ my mom ) A good rule to follow is to capitalize them if they are used as proper nouns. (dictionary.com).
