Troleamesta

In México, sometimes, we use the word "this" like a mild insult... referring to certain male parts; and we combine the demonstrative pronoun "this" with the other words, relevants in the moment.

For example:

Dude: Hey you! your mom is fat!
You: This if fat!! (pointing to your parts)
Dude: =.(....
You (with evil laughter): HA HA HA!

And... you win forever.

So.... this word you see consists in two words, "troll" and "this". Troleamesta its like: Trollmethis!
