Yeah, as Lisa said, they're puns.
Problem is, it's not actually an argument, since it's driven by the 'style over substance' fallacy, as if the person who says it is clever. Puns are not actually arguments, but what Oubliette said: thinly-veiled insults devoid of reasoning, and hence relies on pure emotions to try and dissuade or hurt someone (which usually simply backfires, since mockery isn't compelling).
Puns can serve a purpose to convey a message: in fact, my user name (adamah) is the word for 'ground' in Hebrew, the first man's name is 'Adam' (also generic name for mankind), and the word for 'blood' is 'dam'. That inter-relationship based on word-play actually serves a point to convey a certain message in Genesis: animal blood is NOT to be eaten, but is to be poured on the ground, the same ground (dust) from which Adam was made. Spilling of human blood pollutes the ground, where God was forced to curse the source of life for humans, making it unproductive and even poisoning the land (eg Cain spilling Abel's blood, or unpunished murders in Israel threatened all inhabitants of the land with exile). Of course, God's cursing of the ground ceased after the Flood, since God came up with a better way to address bloodshed: God gave Noah permission to enforce blood-shed by demanding the killer pay with their blood (lex talionis).
However, that relationship is completely lost to most Xians, since most don't read Hebrew, and miss the pun.
Some other vestiges of puns can still be seen in the Bible today in English, where the intent was more to insult, eg the name 'Babel' (as in 'Tower of Babel') is word-play on the name of their captives, the Babylonians, so the pun was a way to passively-aggressively get back at their captors (and even the word "babble" retains the meaning of talking incoherently).
But if you still think a pun is persuasive after leaving JWs, then it probably explains why you were a JW, in the first place: you're likely the kind of person who makes decisions driven by emotions, not logic; worse, you may not even understand the difference, but tells themselves they're completely rational (self-delusion is brutal).
