@shitpostalotl it's a joke dependent upon doing some mental gymnastics with the kana system

basically テ and チ "have the same consonant" according to the kana system, even though one's 'te' and the other's 'chi'

so instead of going ティ to turn the 'te' into 'ti', why not just use チ since it's supposedly "a T- kana" and already has the I vowel

and then we add the dakuten mark to change the voiceless T consonant to the voiced D consonant

and there you have it: "Jizzney"

@shitpostalotl clearly we should all just speak lojban. the logical language. you know, the one where verbs have function signatures you need to memorize.
