AWKWARD....
Are there any words in your language that are difficult or impossible to translate to other languages?
The word "awkward" is that way in English.
Awkward is that perfect blend of embarrassment, discomfort and uncertainty that arises in social situations, either from an uncomfortable silence or because of something someone has either said or done.

Wow...that was an awkward silence!
