Student 1: Have you ever been to Hicks Underground Library?
Student 2: What do you mean, 'have I been there'? I practically live in that place!

A pure racist and/or rapist. Its like eating an Indian, Japanesse, Thai, Mexican burrito while hungover packed with gummy worms, spoiled beans and marsh mellows that are 3years past the expiration date. Vomit inducer.....Look up the definition of "Air Raid" and let your imagination flow. Ever wish you had that magic "wand" that makes everything disappear? Well that would come in handy in an Underground Air Raid....
