English to Spanish Other Cinema, Film, TV, Drama Current (?) slang

The quotation below is not my context, but is is close enough to give you the idea.

So big on the scale of "WTF"S" that its such a shame so many people divided on it . If i was president i would do my best to stich back this wound which clouds the pride of a country and try unite people .

Of course, the "WTF" is this sense or usage of "bewilderment" "astonishment".

My question is, any way to express this in Spanish?

(In this case I would favor any Latin American, particularly Mexican option, over the European version, but I am interested in any good option that will match the register).

Obviously, "la escala de asombro" or "la escala de estupefacción", o algo así, podrían servir conceptualmente (creo), pero algo con un acrónimo entendible, o algo como "quedarse de a seis", (en España, "quedarse de a cuadros", "flipar en colores").

Estoy pensando incluso en algo como "la escala de QC" (¡¿Qué Carajo?!), que obviamente no es de "Quality Control".

Bueno, cualquier sugerencia siempre será de agradecer... puntos o no puntos.

Saludos cordiales y gracias de antemano... ¡QC! ;-)
