‘Fazer das tripas coração’ is the poetic side of tripe …
It is doing things with passion and metaphorically turn vulgarity in nobility, chaotic in order.
It’s the popular expression that describes a superhuman effort to turn adversity into strength and endure setbacks.
Symbolically means strength, vital energy, joy and tenacity facing adversity, capacities in which the people of Porto are lavish.
‘Turn tripe into heart’ is not for everyone.
There in the English language an equivalent expression “to bend over backwards” …. but it’s not the same thing … it lacks the Heart!
