a two word phrase used to describe someone who can't hold their alcohol. the term light weight is only used by drunk people who think that the term lightweight is spelled as light weight (as in two words). refer to other terms that are often misspelled by people who are drunk such as "do" instead of "go". also refer to drunk people who try to text but often create illiterate sentences that even auto correct can not correct .
Mark is so drunk off a half a glass of wine that he thinks that lightweight is spelled as "light weight".
