The kind of wind you break as a result of a full mexiclosure. This happens after eating a full plate of mexican food.... a serious mexican fart!

The farting noise made by an old car that's been beans and riced out.
I saw a 1987 Corolla, looking fresh from the junk yard, turn a corner and speed away. The mexhaust really exploded; I was looking for skid marks.
