What does '들쿗댱' mean?
It's super slang that I can understand it. It is used like this:

들쿗댱ㅎㅎㅎㅎㅎㅎ흐흐흫 아우 그래도 좀 기다렸어염

들다 is to listen right? But I'm not sure if that's the meaning of 들 in the word there. But last sentence is well we've been waiting for you or we've been waiting for brother, right? Kkkk~ Thank you. :)

Answer

I'm not sure if it is proper to study slangs. I would avoid internet and cellphone language.
들쿗당 means 들켰다 (들키다. got caught). They tend to add 'ㅇ' (당, instead of 다) to make it cuter.

아우 그래도 좀 기다렸어염
means "Ugh but I did wait a little"
아우 here means nothing.
