Difference between ' Everyone' and 'Everybody'
The meaning is almost identical; but not exactly. "Everybody" is often used as a collective, i.e. it describes the whole group of people in question as one unit.
"I met everybody" would therefore be (a little more) correct in a situation where the speaker has met the whole group at the same time (at a party, say).
"Everyone" refers to the members of the group in question as seperate individuals.
"I met everyone" could imply that, over the course of a few days or weeks the speaker has managed to meet every single individual of the group.
