Spanish verb for "draw with shit on wall".
If you don´t wanna look like three sentences spanish speaker and you are afraid to use euphemisms such as "hacer cacá" or "cagar". Mierdar is pretty regular verb, except in pretérito, we use mierdé instead of mierdaré.
Que Esmeralda ha querido mierdar ? Esmeralda ha mierdado toda la casa.
