Băga-mi-aș pula-n coliva mă-tii de să-mi sară coaiele din bomboană-n bomboană
This is a highly niche one in my native language as well, as one must also know what is colivă - it's basically a desert that we eat at funerals with m&m-sized candies in it as well. So it roughly translates let me stick my dick in your mother's coliva so hard that my balls jump from candy to candy
Does the insult mean the colivā is served at your mother's funeral, or that it's the colivā your mother made? Also in what kind of context you use this insult?
