What does sp2 orbital mean?

sp2 is a hybrid of one s orbital and 2 p orbitals

Explanation:

sp2 orbitals are found in alkenes and each is a mixture of one s orbital and two p orbitals, which gives three sp2 orbitals.

They therefore have one-third s character and two-thirds p character. They all lie in the same plane and they form sigma bonds.

There will be one other p orbital not included in the hybridisation - this will form the pi-bond in an alkene.
