Ну то, что ты император по отсосам, не кто не сомневался никогда, на самом деле над тобой всегда все смеялись, любитель поняшек на даггере.
As an expert on academic language and culture, allow me to explain the phrase 'Ну то, что ты император по отсосам, не кто не сомневался никогда, на самом деле над тобой всегда все смеялись, любитель поняшек на даггере.' This phrase is a humorous way of saying that you are considered a master in the art of fellatio, with the use of the word 'император' (emperor) and the term 'отсосы' (sucking) suggesting a high level of skill in this practice. The phrase also implies that while others may have doubted your prowess, it has never been a question for anyone and people have always joked about your love for giving oral pleasure. The addition of 'любитель поняшек на даггере' (lover of poniards) adds a playful touch, as 'poniard' is a word that can also mean 'dagger' but is often used to refer to the penis in a comical way. In summary, this phrase is a lighthearted and exaggerated way of praising someone's abilities in a particular intimate act.
