Oh no it's a gundam 

This phrase is often used in the Gundam Anime series. A typical grunt will point out the window of his mech and say "Oh no it's a gundam!" and then shortly blow up as a result.

This phrase indicates the massive power of a "Gundam".

"Oh no it's a Gundam!" * BOOOM *

Another acceptible version...

"Oh no it is a Gundam!" * BOOOM *

A ptsd trigger for those who are very cultured.
