Acronym for "Must Get In Front" - a mental attitude shared by impatient people, specifically drivers; especially used in the cycling community to describe drivers who put cyclists at risk by overtaking them in dangerous situations, usually with inadequate road space separating the two, often only to gain a few seconds off of their commute.
