This technology does not do good enough translation because the output is a gibberish. Someone who is a native Spanish speaker would be able to tell exactly what "because water falls "jaja"" means. Direct and indirect meanings, whatever it might mean.
1. The speaker could be talking about a waterfall
2. The speaker could be talking about a play
3. The speaker could be hinting on something sexual.
In this small context we do not know, especially since "jaja" is not in a standard dictionary but most likely is a cultural reference, and pneumatically we can only guess what it means. (btw, could it be jojo and the guy than saying that water falls up and down?)
and yes I agree with the poster above -- you are being a troll here.
