Place it right after the insult or teasing moment in your edit, then follow it with Emotional Damage and Bruh when the other person tries to backtrack, keeping the sequence focused on the mum joke from start to finish.
About this sound
This Spanish voice clip runs about seven seconds and delivers one indignant line in defence of the speaker's mother, with the emphasis landing on the accusation that someone is laughing at her. It feels protective, dramatic and a little over the top, turning a small insult into a full stand-off. The humour comes from how seriously the speaker takes the teasing, making it a sharp, instantly recognisable reaction.
