Hwyl

[ pronounced hWIL ]
Welsh word to describe a feeling of exuberance and high spirits one might get at a party of anticipated gathering.

• From the TEDTalk below (at about 1:05), by Tiffany Watt Smith, which includes a bunch of emotions where there are no words in English, but which you may well have experienced, but never had one single word to describe them! Or which you may go out and try to see if you can conjure up the feeling from hints in its definition for where and/or under what conditions one might experience it.

This feeling is probably common enough you could remember this word through using it before some, if not many, parties, to describe how you might be feeling.
