Most of us have these little things we are able to do, that are a little different or special. Maybe it is something we mostly use in laid-back social situations, to break the ice and get a laugh. Beyond that, however, this talent does not do much for us. It is clearly not anything we would ever list on a resume. What might you call it?
Intended use:
Mike's family knew he was finally recovering from his injuries when he resumed his _______ of turning everything into a corny pun, which made his nurses laugh.
Another possible use:
Alice: (sticking out tongue and touching it to tip of nose) Tada!
Bob: Wow. Impressive.
Alice: Thanks, but I know that with this _______ and a dollar I can get a cup of coffee.
Candidates considered:
Hobby: On the contrary, your hobby can be of tremendous benefit to you. It is fun for you, releives your stress, and lets you have a sense of accomplishment. (reject)
Antic(s): For me, this has too much of a connotation that you only do the thing to create havoc or to tease another person. (near-miss)
Trick: In the absence of other options, this is what I might go with. However, this still doesn't quite sound right when I read it back. (debatable near-miss).
Despite this, feel free to propose any of these as answers if you can cite definitions and usage examples that refute my objections.
Final word: This is tagged with both single-word-requests and phrase-requests. All things being equal, a single word will win. However, where a short multi-word phrase tells the story better than one word, then so be it.
