Definition:
A much cooler way to say 100,000 , from the Indian Numbering System (pronounced /læk, lɑːk/; abbreviated L; sometimes written lac)
Explanation:
You might hear this used by your Indian colleagues, and in my opinion it should be in general use, as it is not only cool sounding but quicker and well understood.
