Are the words in ALL CAPS phrasal verbs in the following sentences?
1. Long hair should be TIED BACK, and long sleeves ROLLED UP.
2. Never FOOL AROUND in a lab.
3. Hold the plug firmly when PLUGGING it IN.
It depends on who you ask. Some writers seem to regard almost every verb + preposition/adverb/particle combination as a phrasal verb; others reserve the expression for those whose meaning cannot easily be inferred from the core meaning of the two parts.
Personally, I would consider only fool around to be a phrasal verb.
