Translation:You and the beautiful girl are talking on the telephone.
There is a general problem with beauty here. :) It is hard to come up with a one-to-one list of the various words. Maybe all variants should be accepted wherever possible, with a detailed explanation of their differences somewhere.
For "csinos", I would say it is mostly about looks and what someone is wearing at the moment. Well-dressed. Appealing. It could be a not-so-beautiful girl (if such girls exist at all), dressed really nicely for a party, Or a job interview.
And "csinos" can be used for any gender.
"Csinos" is sometimes also used in a metaphorical(?) way. For example, a "nice little sum (of money)" could be a "csinos kis összeg".
