The photo is a tweet. The tweet, written in Turkish, is a humorous complaint about the difficulty of crossing a stream. The joke is about the obstacles animals, in this case antelopes, pose, and the speaker's implication that there's some kind of problem so severe it's better to avoid the area. The phrase "Antiloplar geçmeyin dereden birader" (Don't try to cross the stream, brother, antelopes!) is the setup. The speaker is addressing another person (a "brother"). The next line, "sıkıntı var işte 7 sülalenizi yediler derede" (there's trouble, your 7 family lines got eaten by the creek) is the punchline. This is a humorous exaggeration. It suggests the crossing is so difficult or dangerous that the speaker's family line is in jeopardy. The "7 sülaleniz" is a metaphor to convey serious troubles. Finally, "geçmeyin abi ilerden dolanın artık ya" (Don't cross, bro, go around from the other side, please) is a direct call for caution. The whole message is a humorous way of expressing a potentially dangerous situation, using the antelopes to symbolize something very difficult or troublesome.
Abi bu antilopların 7 sülalesi dereden geçtiyse Atakan'ı da yemiştir 😂
