A female who is a nasty dirty slut. Normally found at venues looking for Molly in minimal to no clothing. They fuck for drugs, alcohol, a roof over their head, or anything materialistic. Their bollos are as wide as a wizard's sleeve and smell like you left a can of tuna, open in the sun.
"That girl was so wasted at the party she ended up half naked on the floor like a cochypuerca."
"That girl right there slept with the crew."
"She is such a cochypuerca!"
