amariconar

A vulgar, derogatory colloquial verb derived from maricón (a slur for gay men), meaning to make someone or something less masculine or 'weaker' by the speaker's standards. It's offensive and homophobic in register, not neutral slang, even though it appears in general dictionaries as an attested word.

• El comentario que hizo fue claramente amariconar el gesto, y sonó ofensivo. — The comment he made was clearly meant to mock the gesture as unmasculine, and it came across as offensive.
• Criticaron el anuncio por usar un lenguaje que amariconaba el producto de forma despectiva. — They criticized the ad for using language that mocked the product as unmanly in a demeaning way.
• Es un verbo que casi nadie debería usar, dado su tono ofensivo. — It's a verb almost no one should use, given its offensive tone.

Assuming this is neutral or merely informal slang because it appears in some dictionaries — it's a homophobic slur-derived term, and using it, even jokingly, will read as offensive to most speakers; there's no neutral context where reaching for it is advisable.
