Your Mom

When someone expresses disbelief or amazement using the phrase 'your mom', often followed by derogatory comments about their mother's abilities or appearance, shocking the listener with unexpected crudeness and often leading to blushing or laughter.

• " When the magician pulled a rabbit out of his hat, the audience yelled, 'Your mom tried harder to make this trick happen!' "
• " After the punchline left the room in stunned silence, the comedian said, 'Your mom's cooking is more appealing to my taste buds' "
• " The electrician's attempt to fix the wires reminded everyone present: 'Your mom would've blown the circuit with her ineptitude' "
