ULOL

Ulol is a Filipino slang term used as an insult meaning "crazy" or "stupid." It is commonly directed at someone perceived as acting irrational or foolish and is widespread in informal speech among Filipinos, especially online.

Origin and usage: The etymology is not precisely documented; it is generally understood as derived from the Filipino word ulol meaning "insane" or "crazy." Over time it shifted into everyday slang to describe a person rather than a mental condition. Its use is more prevalent among younger speakers and in internet culture, with varying intensity.

Social context: Ulol is considered coarse and offensive by many, and its use toward strangers or in formal settings is usually inappropriate. In memes and casual banter, however, it can be deployed with humor or exaggerated emphasis, sometimes to signal disbelief or mockery rather than outright cruelty. As with other insults, tone and relationship between speakers affect how it is received.

Regional and orthographic notes: The form is generally written as ulol, though online posts often employ capitalization for emphasis (ULOL). Spelling variations are limited; the term is widely recognized by Filipino speakers but remains informal slang. In academic or journalistic writing, it is typically avoided or quoted as a direct example of slang.
