A
completely retarded way of spelling 'using'.
Some people haven't been blessed with grade 3 English skills, thus can't tell the
difference between 'u' and 'you'. In many cases people use 'u' instead of 'you' to save time, but some people are so
fucking stupid that the do vice verse.
If you see anyone stupid enough to use the word 'yousing', please direct them to this webpage.
