This is a fun opening, I like to play it in the 2.. Nf6 and then heading into the "Portuguese Variation". Check GM David Smerdon theory about it https://www.youtube.com/watch?v=m2QMY_J4nzM

or instead of 2. e4xd5 Qxd5 3. Nf6
3. Nf6 c4 4. c6 (4. e6 d5xe6 5. bxe6) d5xc6 5. Nxc6

or:
The Icelandic gambit, I think it's called.
This is called dropping a pawn for nothing, not Icelandic gambit.

The real Icelandic Gambit goes like this:
With the crucial difference that after dxe6 Bxe6 the White pawn on c4 not only blocks the scope of the f1-bishop but also leaves a hole on d4 Black can seek to exploit in return for that pawn. Black also has two pieces out and White has none.
or:
The Icelandic gambit, I think it's called.
This is called dropping a pawn for nothing, not Icelandic gambit.
Not nothing, with the extra move black has, through creative play he can develop an advantage.
Not really. The only testing Gambit is c6 not e6. But your birth was a blunder so I dont blame you.
Ok, I was wrong, but you didn't have to say the "birth is a blunder part"
