Some years back (1998, probably) I invented a fragment of spanglish: "hasta you later". According to Google it hasn't caught on yet, but you can help.

On a marginally related note, I just found out that the expressions "curry favor" and "humble pie" are corruptions of (respectively) "curry Fauvel" and "umble pie". Fauvel was a fictional donkey from 1310 that had learned to manipulate important people to brush his hair. Umble means innards. I can't make fun of people who write "expotential" and "lambash" while getting those others wrong myself.
