adj. Consisting of a large number of objects; extreme. Used very loosely as in:
"This program produces infinite garbage."
"He is an infinite loser."
The word most likely to follow 'infinite', though, is hair (it has been pointed out that fractals are an excellent example of infinite hair). These uses are abuses of the word's mathematical meaning. The term 'semi-infinite', denoting an immoderately large amount of some resource, is also heard.
"This compiler is taking a semi-infinite amount of time to optimize my program."
See also semi.
