Mother Insult 

An insult aimed (sometimes pointlessly) towards your mother usually to make you feel embarrased and uncomfortable. It can also be used as a last gasp insult, where the speaker runs out of ideas and consequentally insults your mother.

Mother Insult eg.

Person 1: "I like this new show on tv."
Person 2: "I like your mum."

Man 1: "I like the taste of this."
Man 2: "I like the taste of your mum."

Guy 1: "I was hit hard in football the other day..."
Guy 2: "Your mum was hit hard the other day."
Guy 1: "Really? By who?"
Guy 2: "By me."
Guy 1: *Uncomfortable shiver*

crazy like a Spock who’s just had his mother insulted 

Very, very angry, and probably about to strangle you. It refers to Star Trek's character Mr. Spock, who can be a very pissed off alien if somebody dares mention his human mother, and therefore provokes an emotional reaction in him. It is not, under any circumstances, an advisable move.

First used by Brittany Diamond in her Star Trek TOS commentary.

If someone has to ask about Landrew one more FREAKIN’ time and NOT get an answer, I swear I will go CRAZY like a SPOCK who’s just had his MOTHER insulted.
