the literal definition of this phrase is referring to the bottom of a bag of chips. the slang definition of this phrase was brought about by an instance of a person purposely opening a bag of chips from the bottom and then claiming that it is normal/common practice when it is obviously not common practice. ever since that pivotal moment in history, anything that is uncommonly weird and/or eccentric can be referred to as “bottom of the bag”. this phrase is synonymous with “that’s sus” (as in “that action is suspect”)
