"Waddinator" is a slang term for a semi-retarded student that goes by the name of "Waddington", who is known to bob his head around, and ask questions to his fellow students. His questions usually deal with the topic of metal music, girls, and can be summarized as follows:

"Do you like (band name)?"

"Doesn't (band name) sound like (another band name)?"

Apart from asking these questions, he also has a rather large interest in girls in his school campus. On average, he usually thinks about women 60% of the time, and metal music 40% of the time, but these statistics can change, depending on his hormonal levels.
