To be honest, you can't draw it like a normal S. Draw a box, make sure you do it with a ruler, and make the S in a box shape. Step-by-step below
1. Draw your box (with a ruler)
2. Make a medium size semi circle where the top curve of the S usually is.
3. Do the same with the bottom curve of the S.
4. Curve the edges inside the box slightly so it looks more like an S.
5. Use a 45 degree angle ruler (the triangle one), and from every point draw a line, so it looks oblique.
I really hoped it helped, I tried to explain it as well as I could.
Sorry if it didn't help you enough.
But it should work :).
Draw a line that does not have the same slope of the other line and is not perpendicular too.
A protractor can help you do this. It has a bar that swings and can measure certain angles.
To draw an oblique line, start by marking two points on your paper where you want the line to begin and end. Use a ruler or straightedge to connect these points, ensuring that the line is neither vertical nor horizontal. If you're drawing freehand, simply tilt your hand at an angle as you move your pencil from one point to the other. Adjust the angle as needed to achieve the desired slope of the oblique line.

internal oblique opposes the external oblique
Oblique lines:
oblique rectangular
Oblique means at an angle.
Slanting. A slash (/) is oblique
Oblique means slanted or at an angle.
The inguinal ligament runs deep to the external oblique muscle.
One's a triangle.
