It is often used colloquially and informally in social contexts, such as parties, gatherings, or drinking sessions.
The verb "toast" originally referred to the act of heating bread until it turned brown and crispy, often done by placing it near a heat source like a fire or toaster. Over time, it has come to represent the act of celebrating, commemorating, or expressing good wishes by raising and clinking drinking glasses together. When combined with the adverb "down," it emphasizes the completion or conclusion of the act of toasting. Furthermore, "down" suggests the swift, complete, and often enthusiastic consumption of the drink in one consecutive gulp or sip until it is entirely gone.
While the phrase "toast down" is primarily used in the context of alcohol consumption, it can also be used metaphorically to signify finishing or completing something swiftly, decisively, or in a satisfactory manner. However, it is important to note that the term "tost down" may not be universally recognized or formally defined in standard dictionaries, as it is more commonly encountered in informal or spoken language rather than in print.
