It is important to note that ASL is a complex language with its own grammar and syntax, and signs are not simply one-to-one translations of spoken English words.
The gesture you described might be interpreted in various ways depending on the context and the person's intent, but it is not a recognized sign in ASL.
If you are interested in learning ASL, I recommend finding a qualified teacher or taking an ASL course. There are many resources available online and in your local community.
