In answer to the OP, absolutely not, lines that meet, no matter where, cannot by definition be called parallel
Only holds in the special case of Euclidean. Not true in differential geometry e.g. Riemmanian geometry and so in reality, parallel lines can't exist over infinite distances if we hold fast to that definition.

They keep going "To infinity and beyond"
even I know that and I struggle with basic rithmatic

So what is beyond infinity then? Is it in lockdown?

Beyond infinity is a meaningless concept.

I think it's meant to be Disney's idea of humour or should that be disnae, as in it doesn't matter what number you come up with you can always +1, a bit like wedding invites

No they don't meet, otherwise the wouldn't be parallel.
If they got infinitesimally closer to each other every meter travelled (so no longer parallel), then it would probably take a bigger infinite rather than a smaller infinite.
Possibly they do if you ascribe to the multiverse theories, as in one universe would have parallel lines meeting but still being parallel. Sort of like in one Universe France might have won the rugger world cup.
