A speed head is someone who is tweaked on speed (Amphetamine, Ethylamphetamine, Blue Speed). They will be seen rearranging the cereal in grocery stores, typing fast on a keyboard, doing homework, dancing to music, pacing back and forth, talking a lot, cleaning. Some speed heads will be normally focused but oddly relaxed because of ADHD so they go from hyper to normal.
Normal person: I took 25mg blue speed and alphabetized my music collection. I became hyper.
ADHD person: I took 30mg blue speed and became focused yet calmer.
Third guy: So you're both speed heads.
