Las sospechas

Highly context-dependent. Between close male friends it can be almost affectionate. Directed at an adversary it is a sharp insult. Tone and relationship determine the reading entirely.

Very common in Mexican and US Spanish speech. Can express shock, disappointment, or disbelief. Softened versions like 'no manches' exist for mixed or formal company, but 'no mames' is the raw form.

Widely used to refer to a young man or boy. Not derogatory on its own, though tone can add attitude. Common in Mexican and US Spanish speech.

Placed before a noun to add contempt, frustration, or emphasis. Can range from mildly coarse to strongly offensive depending on what follows and who is speaking. Very frequent in Mexican and US Spanish informal speech.

Short for 'cáete con algo', meaning to hand over money, information, or a favor. Used informally when pressing someone to contribute or deliver.

From 'regar' used figuratively. 'Regarla' means to make a mistake or blunder. Common and mild in tone, an admission of fault without extreme force.
