When you are having sex "doggy style" and all of a sudden you smell something (if one the people had not wipped themselves very well..) that smell is hoobastank
commonly used in lonely island's work, such as The 'Bu, starring Jorma Taccone (sexy), the incredible Andy Samberg and the lesser known (but still cute)Akiva Schaffer, according to him he is the director and doesn't get recognized at the screenings...so don't know exactly how this word pertains to the work...but you should know they use it alot.
The incredibly fragrant aroma of fecal matter from one's insufficiently wiped ass. Typically noticed during doggy style sex from the receiver, by the giver. If you aren't sure what it smells like, take a shit in the toilet and then turn around and stick your face in the bowl and inhale deeply through your nose.
I started pounding Laura last night doggy style but she hadn't finished her paperwork. The hoobastank was so bad I lost my wood and had to try something else.
