A command used by a person in authority to quickly get people into position. Common in theatrical, military, or workplace contexts.
Used either sincerely to show willingness to please or sarcastically. The phrasing is a fixed expression, the meaning is not predictable from the individual words in context.
A very common fixed temporal phrase used to announce a resolution or change. Not slang, but functions as a formulaic expression signaling commitment or intention.
From the verb desgañitarse, meaning to shout or yell until your throat is raw. Used to tell someone to lower their voice or calm down when they are speaking too intensely.
In this usage, todavía pego means the speaker still has appeal or charm. The core verb pegar (to stick, to hit) takes on a figurative sense of making an impact or landing with someone.
