Sometimes it's Tuesday
an expression used to indicate settling for an outcome (or person) less desirable than one would normally achieve. In a bar setting, this phenomenon typically involves significant concessions in the area of beauty, personality, fashion, and the use of footwear and/or personal grooming devices. It is therefore easy and recommended to justify one's action with this phrase.
"Sure, she was wearing her grandmother's elastic-banded safari shorts to the bar, but hey bro, Sometimes it's Tuesday."
