Struggle Booty
A 'struggle booty' is the ass of a woman who is trying hard to keep up with a culture obsessed with big asses, but just doesn't have the mass an ass requires to pass the 'clap with no hands' test. Famous struggle booties include Iggy Azalea's, Eve's, and Wendy Davis'. See Also: struggle cakes
