In English means: "we taught you how to beg, and now you got to the doors before us". It is used to tell someone that he/she mastered a task/job more than the one who taught him/her how to do it. e.g.:
Person 1: "Did you follow my advice for online dating"? Person 2: Oh yeah! I went out with 3 hot chicks last week" Person 1: "what ? I only dated one in a month! it seems 3allamnek 3al sh7edeh, saba2tna 3al bweb!"
"7terna ya ar3a wein baddna nboussik": Lebanese Slang. 7terna means we got confused, ya ar3a means baldness, wein baddna nboussik means "where to kiss you". Literally this expression means "We can't seem to know where to kiss this bald head".
Metaphorically, this expression is used when someone wants to express their confusion about what to do to resolve a certain problem when they have tried many options or many ways of doing so, in vain. It can relate to mundane little things or serious problems.
Sample conversation 1:
Person 1: "did you try reasoning with her"
Person 2: "yes, I sat her down and we had a long chat, and we agreed on what she's going to do, but nothing happened"
Person 1: "did you try warning her?"
Person 2: "yes, then gave her a written warning, she still would not do it: 7terna ya ar3a wein baddna nboussik"!
