undulation:
1. an act of undulating; a wavelike motion.
2. a wavy form or outline.
3. one of a series of wavelike bends, curves, or elevations.

how to use in casual conversation:
"it's not the size of the wave, but the undulation of the seas"
"the undulation of your moods is more than i can stand"
"it wasn't so much dancing as much as it was flailing interspersed with wild undulations"

not to be confused with:

copulation

how it makes me feel:
this one takes me down memory lane. i was first introduced to the word in college biology. we were describing bacterial flagellum when my professor described the "wavelike undulations propelling the organism through the substrate." ahhh. science can be so pretty sometimes.
