Yo I'm gonna teach you how to remember these 5 words by the time you're done reading this post!

_Shrine

yoku = often

YO + KU (as in cool)

This sounds like 'yolk' from egg yolk.
You eat what quite often? Egg yoku that's what.

musuko = son

MU (sound of a cow but shorter) + SU (super) + KO (core)
But pronounced mus-ko

Imagine a mom saying, "I mus you son," to her kid playing a fighting game locked up in his room, trying to KO the opponent.

WA (what) + SU (soup) + RE (razor) + RU (root)

This sounds like the combination of English words 'was' and 'rare'.
You're trying to recall something that wasu reru, but you can't. You forgot.

[O + O] ('oh' but since there are 2 clubbed together, 'ooooooh myyyy godddd!' + I (easy)

A dude who's trying to dig up gold with his friends finally finds it and calls to his friends, "Ooi! I found lots of gold!"

E (ate) + N (win)

There's no start point or en point in a circle. It goes on and on.
