“Lases” is a joke translation for “Reddit”: “Reddit” > “Read it” (as in ‘i read it’) > translated to “Las es” (past tense for “reading something”) or short “Lases”
“Lassmich” in the same style is a joke translation for “Lemmy”: “Lemmy” > “Let me” > translated to “Lass mich” or short “Lassmich”
these translations are grammatically complete bogus and should not be considered “real” ;)
