Another name for BradfordPear trees, namely because of the aroma they emit during the summer. For some reason they produce the exact smell one would find at a gay orgy: hot, raw jizz. The smell can be so strong that one can smell it for miles at a time while driving with the windows down permitting discomfort and nausea.
A terrible site for troubled youth trying to learn chemistry or any other science of such kind. Every wrong attempt will cost your grade to decrease by 10%, just so you can watch your perfect grade go down because you didn't simplify the balanced equation. All in all, you just have zero idea what they want of you. Also, the correct message appears in red. Blood red.
