A naive person who makes irrational, impulsive decisions without thinking through the consequences. Someone who wants to undo all the good work of their patriotic predecessors.
An individual in high authority who acts irresponsibly e.g. Like a teenager who invites everyone to her house party on social media. They have a great party but in the cold sober light of the next day, the gatecrashers have wrecked her parents house. A Merkelist will do this with a whole country, or even worse, an entire Union of countries!
The policies of that party are going to bring havoc to this country, their leader must be a Merkelist.
When you're playing a video game and the matchmaking puts the absolute worst shitheads on your team, you have been Menked. Named after celebrity Dr. Joshua Menke, the Lead Engagement Designer for Halo 5 and all the terrible matches he's caused after implementing TrueSkill2.0. Excuses he'll use to justify the matchmaking: "Even though their rank is plat and they played like a silver, their mmr is actually onyx," "The population of that playlist was too low, so the mm expanded the parameters and just happened to put everyone bad on your team" and "It's working as intended"
Gamer1: I was doing great! Dropping a 30 bomb! But I got Menked!!!! Each teammate went neg 15! Can you believe it?
Gamer2: Yeah dude, I was getting Menked all last night. Makes me hate Halo these days...
