A High Yield Portfolio (HYP) seems to me a harmless and generic name for any group of investments cobbled together in an attempt to bring in above-average income. Until recently I had no idea of the origin of the term, which is common enough in the FI blogs and even the MSM.
However, to the boys over at The Lemon Fool forum, HYP is a religion. It has its own messiah, texts, rules, specific and tightly-moderated forum boards and a gaggle of hard-line disciples, with a kill-the-heretic mentality for anyone daring to suggest actually selling portfolio shares or including investment trusts etc.
The constant bitching that goes on between the strict adherents and the heretics is actually quite amusing. Check it out, they're in top form at the minute ...
It reminds me of Graham Chapman in the Life of Brian asking 'are you the Judean People's Front ?'
