Kyon, mainey kya kaha, or better yet, meray kehnay say kya matlab ya nateeja nikaala? 
Ugh is used to express digust or annoyance for something that you find distasteful or that you don’t look forward to. Example: Ugh..I have to clean the bathroom again.
Err or **errm **is an embarrassed or cautious version of “uhm”. Example: Errm…your fly is open.
I think you mean aarghhhhh…which is used to express annoyance, frustration (out of confusion perhaps), anger, hopelessness. Example: Aaargh!!! I have so much work to do you and keep bugging me!

i guess you use ugh to show disgust or express annoyance or something like that
err…when u dnt really knw what/how to say something…that is when u dont have an exact answer…or maybe someone has asked a question whose answer is quite of, so u answer it preceding with an ‘errr’, maybe to show contempt?
and aargh when u u’re annoyed, or scared…say u forgot to do something: aargh i havent done my homework…or the cleaning example posted by someone before
Then don’t read it.
