i have no idea what to really put as my passwords, it is just keysmash and it saves to my icloud, but sometimes icloud doesn't work and i forget, what are some good ideas for passwords? things to base your password off, like pet names and places, i'd do that, but everyone knows my favourite places and pets names
You actually already have part of the answer: to make it easy to type, use only lowercase letters.
Now the trick is to know how many letters to use. If you want, e.g., 40 bits of entropy (a quite high goal for a password), then you must accumulate at least x letters such that 26x > 240 (i.e. 9 letters). 9 letters are sufficient if they are chosen uniformly, randomly and independently from each other; do not try to do it in your head, the human brain is a terrible RNG. Instead, use a good RNG (coin flips, dice, a computer with /dev/urandom...) and, that's the important bit, stick to the result: you get your 9 letters, accept them and learn them.
If you want to have a password that you can "easily" memorize then you need more letters. For instance, you could generate 100 sequences of 10 letters, and keep the one which pleases you most; since 2610 > 100*240, you still get your 40 bits of entropy.
See this question (in the crypto-specific stackexchange site) for details on the involved mathematics.
Hmmm, it seems you have already considered that know-it-all horse. In my experience, that (lowercase pass-phrase of multiple words) is the easiest option without a special app - each operation gets you one additional character (as opposed to special chars, where multiple operations get you one character).
Apart from that, there's a (cross-platform) app named Keepass, also available for Android (free, for 1.5+, IIRC); I'm using the clipboard to ferry passwords to and fro, clearing it afterwards - thus the annoyance of password management is independent of password length and type, allowing for arbitrary password length. I'm also using Dropbox to sync the (encrypted) password file with my desktops.
