The photo is of four tweets from Turkish football player Merih Demiral. Each tweet says "Hayırlı Cumalar" which means "Happy Fridays" in English. However, the dates on each tweet are in the form "DD Month YY" and the months are in Turkish: "Tem" for July, "Haz" for June. This creates a joke because "Temmuz" (July) and "Haziran" (June) are both months, but the shortened versions sound like a single word: "Temhaz" in Turkish. It's a play on words that makes the tweets humorous and relatable to Turkish speakers. The joke is that Merih Demiral is wishing people "Happy Fridays" on dates that are not actually Fridays.
