DACAracha
An extremely racist term for a DREAMer, an undocumented immigrant minor brought to the United States as a minor. The word is a portmanteau of DACA (Deferred Action for Childhood Arrivals), a program instituted by President Obama to protect the DREAMers from deportation, and "cucaracha", the Spanish word for cockroach.
Josualdo's English teacher is secretly a Republican. At home, he refers to his undocumented students as DACArachas.
