Literally 'you looked for it.' A fixed phrase used to tell someone they caused their own misfortune through their own actions. The reflexive buscársela is the underlying construction.
From the verb largarse, meaning to leave quickly or abruptly. Very common throughout Latin America as an informal, emphatic way to say someone is leaving, often with a sense of impatience or defiance.
Bocota is an augmentative of boca (mouth), carrying a contemptuous or exasperated tone. The phrase is a sharp, informal warning to stop saying offensive or inappropriate things.
The construction deber + infinitive in colloquial speech often functions as a strong informal obligation rather than a polite suggestion. The object pronoun me intensifies the personal claim the speaker is making.
Carcomer means to gnaw or eat away, and entrañas refers to the inner organs or deepest feelings. Together the phrase conveys intense guilt or worry consuming someone from the inside. Used figuratively.
