Air quotes (also called finger quotes or bunny quotes) refers to using one's fingers to make virtual quotation marks in the air when speaking. This is typically done with both hands held shoulder-width apart and at the eye level of the speaker, with the index and middle fingers on each hand forming a V sign and then flexing at the beginning and end of the phrase being "quoted."
A hand gesture resembling a quotation mark acting as the verbal equivalent of a quotation mark. Since quotation marks are usually used in pairs the plural air quotes is more common
a movement that someone makes in the air with their fingers to show that what they are saying should be in quotation marks, and that it should not be taken as their real opinion or their usual way of speaking
