We come across slangs when we are

watching films,reading popular news

papers or novels.

But foreign students should not use slangs

very often because they can cause offence

to some sections of the population. 

 Fortunately we can still make use of some

dinosaurs: good dictionaries to look up

slangs or

check  online dictionaries which can make

us ,foreigners , to avoid trouble or offend

people we do not know very well.
