A Mexiscreamer is any number of unattended and ignored and/or screeching, yelling and howling Mexican children who shatter any and all peace you might find in public. Not to be confused with banging a loud Mexican slut.
We went to the beach and swarms of mexiscreamers were running around howling and we had to move our chairs. This happened last week at the mall too. Little Rigoberto was ignored by his parents and assaulted all of our senses.
