how would you say "catchy" in Russian -- as in "a catchy tune"
the translations in the dictionary don't seem like the right kind of words -- I might be wrong, though

and

is there a Russian equivalent to "who cares" ?

thank you,

How do you convey that someone is not a person that you would want to fight because he is a tough guy? I'm looking for a Russian equivalent to a word like 'badass' or a word or phrase to say that someone is a dangerous person.

What is the proper word for 'thug'? Looking it up on translators and online dictionaries gives убийца, головорез, бандит ... all kinds of stuff.

Is there a phrase that conveys that someone is a 'connected guy' (that he has friends in the Mafia, or is part of a gang)?

Finally, is there a single verb that has the meaning that someone is carrying a gun or weapon? Something like an equivalent to the American slang 'to be strapped'?
