• When asked for a vote to save, responds with "I'll try" and then voting against them anyway.
• "Me and my best friend aren't f2 and haven't whispered all game, why are you splitting us up."
• "I'm not a threat, so you guys are so stupid for voting me out."
• Players taking the game personally.
• Thinking that people suddenly trying to be best friends with you is genuine when they are simply looking for safety because you just won HoH.
• Thinking that you're the only one "playing the game"
• Refusing to vote for the player that "had to win challenges to stay in" in jury because you were too strategically inept to vote them out before they went on to win the last few challenges in a row.
• Thinking that there's only one "right" way to play the game
• Arguing that you technically didn't betray your f2 because they weren't your "first f2 deal".
• Players taking the game personally.
• Thinking that a flashy game automatically means good gameplay.
• "I said I wouldn't nominate you... but I didn't say anything about renom after pov... so technically I didn't lie..."
• Pretending to use random.org to decide the nomination. - Facewall bonus if they post a screenshot of whatever number they got.

• Tryharding in the d1 HoH only to nominate newbies.
• Thinking that there's only one "right" way to play the game
• Players thinking that alliances are meant to be upheld all the way till final 2.
• "If you didn't win in challenges you clearly floated your way to the end"

• Suiciding out of the game because the game isn't going your way.
• Deluded people that think they got out for being a threat when they simply sucked at the game and didn't deserve to stay.
• Pretending to have no opinion or power on anything.
• Continuing the "no opinion" charade by pretending to use random.org when winning HoH.
• "I'm not a threat, so you guys are stupid for voting me out."
• Announcing out loud that you're not going to kiss the HoH's butt, because for some reason you think that it's different from whispering them
• When you betray your closest ally because "they are a huge threat" and then you get voted out next.
• Being deluded enough to think that you played better than someone else only because you made it further than them.
