Current slang term for 'cool' or 'hip'
My character is a student at Oxford, and is around 20-years-old. He's British by birth with a Spanish mother and is bilingual. He tells an older man that a certain Spanish endearment is very old-fashioned, and offers to teach him some others that are cooler or more hip.
I'm in my 50s. I have no idea what word a British 20-something would use instead of 'cool' or 'hip'. (I have no idea what American students would say.)
Suggestions?
ETA: The older man does not speak Spanish, and the student knows this. The conversation begins with the older man asking for the meaning of a Spanish phrase. The student teases him in a friendly way, asking if he's planning to flirt with a lovely señorita. The older man (in his late 50s) says no, he's just curious. He overheard someone else say it. (He doesn't explain that he accidentally overheard it during a co-worker's phone conversation.)
