Recently a graphic began circulating on facebook, pinterest, etc. suggesting that the lines on Solo Cups were intended to indicate proper sizes for popular alcoholic drinks (liquor, wine, and beer):The Solo Cup company responded by posting a message on its facebook page , explaining that it never intended the lines to mean any such thing.

Evidently it was worried about being seen as promoting binge drinking, so it offered some non-alcoholic drinks that the lines could also be used to measure, such as water, juice, and chocolate milk.
