Venezuela's opposition protests this week may be the messiest in a six-week wave of unrest as demonstrators prepare to throw faeces at security forces, adding to the customary rocks, petrol bombs and tear gas.
The new tactic has been dubbed the "Poopootov" in a play on the Molotov cocktails often seen at streets protests in Venezuela.
"They have gas; we have excrement," reads an image floating around social media to advertise Wednesday's "Sh** March."
With inflation in the high triple-digits, shortages of the most basic medicines, and millions suffering food scarcity, the country is undergoing a major crisis.
For weeks, hundreds of thousands of people have taken to the streets, angry at the government of unpopular President Nicolas Maduro.
Marlene Berroteran, a 62-year-old demonstrator, said she was protesting because the government had taken everything from her, down to her fear. She lamented what she called repressive tactics by government forces and the deaths caused in the unrest.
Since the anti-Maduro protests began in early April, at least 37 people have died, with victims including supporters of both sides, bystanders and members of the security forces.
Some opposition sympathizers are appalled at the plans to use faeces, both animal and human, calling it an unsanitary and inappropriate tactic even in the face of a government they despise.
Many note that throwing faeces could increase cases of infectious diseases which are soaring due to the lack of medicine as well as basic cleaning materials such as soaps and disinfectant.
Messages have been going viral on Venezuelan WhatsApp groups giving step-by-step instructions and advice on putting together the Poopootov cocktails.
Some insist on avoiding glass containers to ensure that the projectiles only humiliate troops rather than injure them.
With opposition leaders looking to bring frontline government forces onside, given they too suffer from the country's crisis, the strategy may backfire.
Many are thought to sympathize with protesters' complaints about the economic situation but do not speak out for fear of retaliation by authorities.
While the opposition coalition has remained quiet on the strategy, some lawmakers have given it tacit acceptance.
"They use their weapons against us, so people are using what they have," said lawmaker Rafael Guzman, who on Monday was seen in the thick of tear gas throwing a canister back at security forces.
