Un ganador, una canción

Playful Argentine expression built on 'pesado' (heavy/annoying). A 'collar de sandía' is a watermelon necklace, i.e. something absurdly heavy to wear. Used humorously to describe someone who is tiresome or burdensome.

Argentine colloquial phrase. 'Vagar' means to wander aimlessly; 'vagar la pena' means to drift about consumed by sadness or self-pity, often used critically of someone who refuses to move on.

Argentine fixed expression used after something obvious has been stated. Roughly equivalent to 'couldn't be more obvious if you tried'. Often said ironically, underscoring that something was already perfectly clear.

A colorful compound insult. 'Lechuza' (owl) suggests someone who watches everything with a wise or prying air; 'sabelotodo' is 'know-it-all'. Used mockingly toward someone who constantly offers unsolicited opinions or corrects others.

Literally 'everything rots'. Used as a warning or prediction that a situation will collapse or deteriorate badly if something is not done. Carries a strong, somewhat dramatic tone.
