Claim 3:
4. A golf tee comprising:
a support inserted into the ground; and
a rotary portion rotatably coupled to the support and having an upper surface on which a golf ball rests,

the support comprises a pointed insertion portion formed at a lower portion thereof and inserted into the ground and a coupling portion formed at an upper portion thereof, protruding above the ground, and coupled to the rotary portion;
the coupling portion of the support is inserted into and coupled to the receiving portion of the rotary portion; and
the coupling portion has a protrusion formed at a portion of an outer circumferential surface thereof and the receiving portion has a receiving groove receiving the protrusion therein such that the support and the rotary portion are vertically aligned with each other with the protrusion received in the receiving groove,
wherein the rotary portion further comprises:
multiple cutouts formed in the receiving portion to allow the receiving portion to be elastically deformable such that the coupling portion of the support is coupled to or separated from the receiving portion; and
