Teamplayer, Ego Shooter, First Person Shooter
In German, the word "Ego Shooter" is often used for "first person shooter". This may be due to the fact that "Erste Person" (first person) is not a common forms to describe perspective. Instead, we say "Ego Perspektive" for "first person" and so developed the term "Ego Shooter". Unfortunatley, the word ego may also refer to egoism and it was just a matter of time until "Ego Shooter" is used as a dysphemism, for example here as an opposition to team player:
„Wer wird zum Teamplayer, wer zum Ego-Shooter, wer überwindet seine Ängste, wer wird der neue Dauerpatient von Dr. Bob und wer wird 2017 König oder Königin des Dschungels?“ (TV channel RTL in an announcement)
"Who will become team player [and] who will become Ego Shooter [...]"
