A person who dawdles; someone who moves slowly or wastes time by lingering instead of hurrying.
From 'dawdle' (to move slowly or waste time) with the agent suffix '-er,' creating a noun for someone who habitually engages in the action.
School hallways and trains are full of dawdlers, and the word is so relatable that it appears constantly in literature as a character type—the person who misses the bus or delays everyone else.
