A weekend day in which some friends drink large amounts of alcohol are consumed, revealing a type of alter ego that is loud, arrogant and obnoxious. The "abe" comes from a play on the word obnoxious, with the change going from "ob" to "abe." Hence when someone expects to be shitfaced they might say, "Abe (noxious) will be out tonight." This can also occur on other nights, such as Fridabe.
