Essentially, a "shit fight". A defecation altercation is an expression of extreme anger and frustration. Occasionally, it may be synonymous with "shit fit", or the throwing of feces.
What ya get when ya move da "c" from da first word to da second. Since "Sergio" is a Spanish name, maybe this term refers to a dust-up dat occurs in a Mexican hospital during a disagreement over a tummy-tuck, breast-augmentation, sex-change operation, etc.
Some people are so horrified at their post-facelift appearance dat they actually get into a surgial altercation with dadoctor or other staff.
A little known technique for fitting the max amount of people into the backseat of a car. If done properly, 4maybe even 5 people will be able to comfortably ride in a 3 person backseat.
It consists of having the first person who gets in the back seat sitting with their ass either touching the backrest(as you would normally ride) or sitting with their ass as close to the edge of the seat(and as far from the backrest) as possible. From their, everyone alternates ass to front ass to back until you can't fit anymore people.
This is proven effective.
