You could say he's a bad person; he's always trying to cause problems for others, creating conflicts or drama. He's a big liar, but he doesn't do it with bad intentions; he doesn't know it's wrong. Although he's a bit too friendly with his friends sometimes, if you play along he'll be your friend; he's very fair.
Speaks in brisk, checklist-like bursts; slips in dry jokes about weeds and leaks.
