Nothing a teenager loves more than learning something along the way

Point of order, OP asked for disused words, not frequently used words.
Not so much disused but rarely used these days:
-
Nincompoop. (Fun fact: it’s a mangling of Latin “non compos mentis” = “not of sound mind”)
-
Gibbering wretch.
-
Navel starer.
-
Halfwit.
-
Dunce
Actually rare / disused:
- Flibbertygibbet. Means “airhead” which itself is a kind of weird word, but is better known. Both usually applied to girls and young women, but can also be used for males, etc.
-
