Heeeeeeeeeeeeeeeelp

It is
مدد
but he wrote
مداااااااااااااااااااااااااااد
as if he is prolonging his voice like Sufi followers.
Anyway, he said this word in his comment in a sarcastic way resembling Obama to the Sufi Sheikhs that the ignorant people seek help at their shrines though those sheikhs cannot help themselves...

By saying this word, he pretends that the speech of Obama made him appear as if he were a Muslim Sheikh that we believed his words. Accordingly, he seeks help from him...

So, the expected reaction is to roll on floor laughing at this funny comment. We may resemble this situation where a religious Christian who listens a clergyman of another religion that sweet talked about Christianity and at the end he sarcastically asked him an Eucharist...
HTH
